Staging files as a group saves both MSS time and your time. The MSS will get all the files that are on one tape off the tape at the same time rather than having to mount the tape each time an individual file is retrieved. Once the staging has been completed, you can view or retrieve an image in just the time it takes to move the image from the MSS to your machine, without encountering the 5-10 minutes wait that it can take for the file to be brought in off tape. The following information is kept about each collection. The derived images may be gif or jpeg format.
Higher numbers give better quality, but create bigger files.
Not all browsers support in-line jpegs. Netscape, Internet Explorer, Mosaic and HotJava all do. In my experience, jpeg down to quality 50 looked as good as gif viewed with Netscape on a Unix machine, but not as good when viewed with Netscape on a Mac. The access groups and users are defined by the Image Library software and are independent of Unix users who have accounts on the server machine. Any collection owner can create new users or groups for his collections.
