Claim Text:
1. A method of delivering images by an edge server to a web browser, comprising: receiving through an interface a request for an image file; detecting by a processor the image file as a non-interlaced image file; converting by the processor the detected non-interlaced image file to a corresponding interlaced image file; sending a first segment of the corresponding interlaced image file in response to the request for the image file, wherein the first segment of the corresponding interlaced image file is received by a Document Object Model (DOM) virtualization client, wherein the DOM virtualization client is injected by adding JavaScript client code in a head section of a webpage file associated with the image file; and delaying delivery of a second segment of the corresponding interlaced image file until a subsequent request for the second segment of the corresponding interlaced image file is received, wherein the subsequent request for the second segment of the corresponding interlaced image file is sent by the DOM virtualization client, and wherein the sending of the subsequent request is kept transparent to the web browser.
