DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Reference is now made to Fig. 1, which is a simplified partially pictorial, partially block diagram illustration of a system and methodology for displaying information received over the Internet in accordance with a preferred embodiment of the present invention. As seen in Fig. 1, a web browser 100, such as Microsoft Internet Explorer 5.5, typically resident on a PC, such as a Dell Dimension L733 running Microsoft Windows 98, receives a web page 101, such as an HTML page, over the Internet from a web server 102. The web browser 100 preferably includes visualization functionality 103 which interfaces, typically via the Internet, with an image server 104, such as a Dell Power Edge 2450 running Apache 1.3.12 on an OpenBSD 2.7 operating system. The image server 104 interfaces with an image database 106, which is preferably a Dell Power Edge 2450 running MySQL 3.23.25 on an OpenBSD 2.7 operating system which is preferably loaded by using functionality of the type described hereinbelow with reference to Fig. 7. The visualization functionality 103 is operative to download via the image server 104 from the image database 106 images of web pages which are referenced in hyperlinks contained in the web page 101 and to provide to a user, via the web browser 100, an annotated web page 110, which preferably includes the web page 101 having alongside it images 112 of homepages linked with web page 101. Reference is now made to Fig. 2, which is a simplified partially pictorial, partially block diagram illustration of a system and methodology for displaying information received over the Internet in accordance with another preferred embodiment of the present invention. As seen in Fig. 2, a web browser 200, typically resident on a PC, such as a Dell Dimension L733 running Microsoft Windows 98, interfaces, typically via the Internet, with a web server 202, such as a Dell Power Edge 2450 running Apache 1.3.12 on an OpenBSD 2.7 operating system. The web server 202 interfaces with a dynamic page generator 204, such as a P.H.P. 4.0.2, in which is preferably installed a visualization functionality 206, which is described hereinbelow in greater detail. The dynamic page generator 204 interfaces with a database 208, such as a Dell Power Edge 2450 running MySQL 3.23.25 on an OpenBSD 2.7 operating system. The web browser 200 preferably interfaces with an image server 210, such as a Dell Power Edge 2450 running Apache 1.3.12 on an OpenBSD 2.7 operating system. The image server 210 interfaces with an image database 212, which is preferably a Dell Power Edge 2450 running MySQL 3.23.25 on an OpenBSD 2.7 operating system, which is preferably loaded by using functionality of the type described hereinbelow with reference to Fig. 7. The visualization functionality 206 is operative to embed within a dynamically generated web page, such as an HTML page, commands to the web browser 200 to download via the image server 210 from the image database 212 images of web pages which are referenced in hyperlinks contained in a web page 213 and to provide to a . user, via the web browser 200, the web page 213 annotated to include therewithin images 216 of homepages linked therewith. It is appreciated that either or both of the embodiments of Figs. 1 and 2 may provide images of web pages which are referenced in hyperlinks contained in a web page either alongside or within that web page. It is also appreciated that either or both of the embodiments Figs. 1 and 2 may provide images of web pages which are referenced in hyperlinks contained in a web page, which images hover either over or alongside the hyperlinks. It is appreciated that the visual image of another web page may function as a hyperlink. Reference is now made to Fig. 3, which is a simplified flow chart of part of visualization functionality employed in the system and methodology of Fig. 1. The flow chart of Fig. 3 illustrates generation of a list of hyperlinks from a web page, such as web page 101 in the embodiment of Fig. 1 received from a web server 102. As each link is extracted from web page 101, an examination is made in order to eliminate links which refer back to web server 102 and to determine whether redirection links are present. This is typically done by searching for the presence of a string "http://" encoded in the URL, which characterizes a redirection link. In the case of links, which appear to be redirection links, only the ultimate destination is listed In the case of links which do not appear to be redirection links, the links themselves are listed. The resulting list is employed as an input to the functionality of Fig. 4. In the illustrated embodiment of Fig. 3, all of the hyperlinks are processed. Alternatively, not all of the hyperlinks need be processed. In such a case, a user may decide which hyperlinks to process. Reference is now made to Fig. 4, which is a simplified flow chart of visualization functionality employed in accordance with a preferred embodiment of the present invention. As seen in Fig. 4, a list of hyperlinks is received. This list may be derived from a web page such as web page 101 in the embodiment of Fig. 1 using the functionality of Fig. 3 or may be provided by dynamic page generator 204 and obtained via database 208 in the embodiment of Fig. 2. If hyperlinks are present, the URL of each hyperlink is split into URL components. For example, if the URL of a hyperlink appears as follows: http://www.microsoft.com:80/windows2000/upgrade/compat/search/ comρuters.asp?ρage * =2&send=l&Order=Sort+by+Comρany&CN=Dell&PN=&PT= The components thereof include the following: Scheme: http Host: www.microsoft.com Port: 80 Path: /windows2000/upgrade/compat/search/computers. asp Query: page=2&send=l &Order=Sort+by+Comρany&CN=Dell&PN=&PT= The path component may be trimmed based on the consideration of finding the most representative image of a given web page. A flow chart illustrating a preferred algorithm for making this determination appears in Fig. 5 and is described hereinbelow. Thus, in the above example, the trimmed path component appears as follows: Λvindows2000/upgrade Following any trimming of the path component, a new URL is constructed from the scheme, host, port and trimmed path components. This URL is employed for outputting an http query to an image server, such as image server 104 in the embodiment of Fig. 1 or 210 in the embodiment of Fig. 2. A preferred form of http query in the above example appears as follows: http ://wb 1. girafa. com/srv/i? u=http;//www.microsoft.com%2fwindows2000%2fupgrade Reference is now made to Fig. 5, which is a simplified flow chart of path component trimming functionality employed in the embodiment of Fig. 4. As seen in Fig. 5, the path component trimming functionality comprises receipt of the URL components after splitting thereof, as described hereinabove with reference to the flowchart of Fig. 4. Information from the host component of the URL is employed in trimming of the path component of the URL. Each path component comprises a plurality of path segments. If the last path segment in a path component is a file name, this path segment is removed. Determination whether a path component is a file name is typically carried out by examining the suffix thereof to determine whether it is a known suffix representing a file name. If the first path segment starts with a "~", which typically designates a home directory in a Unix system, the path component is trimmed after that first path segment. If the host is not www.geocities.com, the path component is trimmed after the second path segment. If the host is www.geocities.com and any of the first three path segments consists of 4 digits, the path component is trimmed after the first segment that consists of 4 digits. If the host is www.geocities.com and none of the first three path segments consists of 4 digits, the path component is trimmed after the second segment. Reference is now made to Fig. 6, which is a simplified block diagram illustration of a system for generating an image database useful in the system and methodology of Figs. 1 and 2. As seen in Fig. 6, a controller 600 receives a list 602 of homepages, the images of which it is desired to download into an image database 604, such as image database 106 in the embodiment of Fig. 1 or image database 212 in the embodiment of Fig. 2. The controller 600 operates a multiplicity of downloaders 606 simultaneously by supplying to each downloader one URL at a time. Each downloader 606 retrieves from the Internet, the homepage and the embedded objects corresponding to the URL supplied to it by the controller 600 and deletes therefrom executable block content. The resulting output of the downloaders 606 is supplied to a web server 608 via a database 610. Each downloader 606 establishes a connection with one of a plurality of thumbnail generators 612 via a broker 614. Once this connection has been established, a URL of a locally stored copy of a downloaded homepage, which is stored in database 610, is sent to the thumbnail generator 612 with which the connection has been established. - - -- ' Each thumbnail generator 612 operates a corresponding web browser 616 to download via web server 608 the locally stored copy of the homepage, which is stored in database 610. The thumbnail generators 612 each receive a rendered image of the homepage from a corresponding web browser 616 and shrink it and supply it to the downloader 606 -with which the connection has been established. It is appreciated that normally the number of downloaders exceeds the number of thumbnail generators by at least an order of magnitude. The broker 614 coordinates interaction between a thumbnail generator and a downloader. Reference is now made to Fig. 7. which is a flow chart illustrating operation of a controller forming part of the system of Fig. 6. A list of homepages is received from database 602 (Fig. 6). Each homepage is taken from the list and downloaded by a downloader 606 " (Fig. 6). The functionality of Fig. 7 ensures that a predetermined number of downloaders operate simultaneously, so long as the list of undownloaded homepages is sufficiently long. Reference is now made to Fig. 8, which is a flow chart illustrating operation of a downloader forming part of the system of Fig. 6. As seen in Fig. 8, each downloader maintains a download queue for the homepage which the downloader is currently downloading. The download queue includes a list of URLs of objects in the homepage as well as the homepage object that require downloading in order to provide a local copy of the homepage. For each URL in the download queue, an inquiry is made whether a local copy of the object corresponding thereto already exists. If so, a link to that local copy is created. If not, an attempt is made to download the object. If upon attempting to download the object, the downloader is informed that the object is located on another URL, i.e. by the receipt of redirection reply, that URL is placed in the download queue. If, the download is successful, the downloaded object is stored in database 610 (Fig. 6) as a local copy. If the downloaded object is an HTML page, then the HTML page is processed, preferably by an algorithm of the type described hereinbelow in Fig. 9. When the download queue is empty, a connection is established with thumbnail generator 612 (Fig. 6) via broker 614 (Fig. 6). The URL of the local copy of the homepage object is sent to the thumbnail generator 612 and a thumbnail image of the homepage is generated hereby. This thumbnail image is stored in image database 604 (Fig. 6). Reference is now made to Fig. 9, which is a flow chart illustrating operation of a process HTML algorithm employed in the downloader of Fig. 8. The HTML object which is downloaded is scanned, the executable content thereof is eliminated and embedded objects therein are recognized. For each embedded object a decision is made whether to download it. This decision is made based on the nature of the embedded object and the nature of the reference thereto. Generally, images and HTML objects are downloaded. URLs of objects to be downloaded are placed in the download queue referred to hereinabove in connection with Fig. 8 and the HTML object is modified to refer to the local copies of the objects to be downloaded. References to objects not to be downloaded are eliminated from the HTML object. Reference is now made to Fig. 10, which is a flow chart illustrating operation of a thumbnail generator, such as thumbnail generator 612, forming part of the system of Fig. 6. Initially, the thumbnail generator initializes a web browser functionality 616 (Fig. 6). When a connection is established to the thumbnail generator 612 from a downloader 606 (Fig. 6) via a broker 614 (Fig. 6), the thumbnail generator 612 receives the URL of the local copy of the homepage. The web browser navigates to that URL and renders the homepage. A snapshot of the homepage is taken, typically in bitmap form. This snapshot is resized to a desired thumbnail size and is then transmitted via the downloader 606 for storage in image database 604. Reference is now made to Fig. 11, which is a flow chart illustrating operation of a broker, such as broker 614, forming part of the system of Fig. 6. The broker receives connection requests from both thumbnail generators 612 (Fig. 6) and downloaders 606 (Fig. 6). When simultaneous requests are pending from both a thumbnail generator and a downloader, the broker establishes a direct connection therebetween. When there exists a surplus of connection requests from either thumbnail generators 612 or downloaders 606, queues of such connection requests may be maintained by the broker. It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described hereinabove. Rather the scope of the present invention includes both combinations and subcombinations of the various features described hereinabove as well as variations and modifications which would occur to persons skilled in the art upon reading the specification and which are not in the prior art.
