I can not read the files back using other gif programs such as Giffer 1.08 and QuickGIF 1.0. It there a patch? The problem is that the latest versions of GIFConverter (from 2.2d4 on, I believe) are now correctly tagging GIF files as being "GIF89a", rather than the older "GIF87a". It does this because GIFConverter makes use of some of the newer GIF89a features (multiple images in one file, etc.). Older versions were incorrectly tagging these files as "GIF87a" files. Unfortunately, there's no option that says, "I'm just saving a plain old GIF87a file with no special features, so please tag it as such." You can achieve the same results by opening and resaving the file with an older version of GIFConverter (2.1.1 works fine). You can also open the file with something like SUM Tools and change the "GIF89a" to "GIF87a" at the beginning of the file. That's what I do when I upload files to my Unix box at work (except I use Emacs instead). -- Steve Baumgarten | "New York... when civilization falls apart, Davis Polk & Wardwell | remember, we were way ahead of you." baumgart@esquire.dpw.com | cmcl2!esquire!baumgart | - David Letterman
