Re: 1GB XD pic card..........
Do you mean, you use Winzip or some program to compress one or more of your pictures (jpgs) into a zip file? ZIP file will not modify your JPGs, so your JPG pictures would be the same quality before and after the zip process.
JPG itself is a way to compress the original picture that your camera took. On some cameras, you can specify the quality of your pictures (not only resolution), and that determines how much the camera will try to compress the original picture. See link below for example pictures of different JPG qualities. Because JPG is already a compressed file, Winzip or other compression program usually can not compress it much smaller. Some camera allows you to save the pictures in RAW mode, and there is no JPG compression there, so in theory, the picture have more details. And you would be able to use Winzip to make the file smaller.
Here is a link that explains JPG in more details

Based on the file size, the files in question are probably RAW, not jpg files. Nikon View NX software or Photoshop will be able to open those files. You may want to convert them to jpg files, but do keep the RAW files since they contain much more picture detail then the jpg files.
Deleting or formatting won't make the data in xd card erased permanently.
Those deleted data is still stored on the xd card, it's just invisible or inaccessible. Only the FAT or NFTS table is erased (the information about where those data were saved), but the real data are still intact there in sectors of xd card .
So as long as those data are not overwritten by new data, it's highly possible to recover them. And the MOST Effective way is to rely on some format recovery programs.
Try asoftech data recovery program, which can recover data after deeply scanning your xd card drive to look for lost data you accidentally deleted or formatted.
its the card not the camera.
i think you fingers have come into contact with the gold bits on the xd card.
