Tina, The file format shouldn't be a problem. Macs can create and read both tiff and jpeg files, although i do know that there is an IBM tiff and a Mac tiff format. Nevertheless, as long as the person using the files has access to reasonably good softare, they should be convertible. The readability of the disc is likely to be a bigger problem. Sounds like you are going from a PC? I know that with my Mac equipment I can burn PC-readable discs. Good software on your side therefore should allow you to format a disc the other way around, in a Mac format. There are also programs, I believe, that will burn a hybrid disc with the same data readable by both platforms.
Hope that helps. Colin __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo! Mail. http://personal.mail.yahoo.com/
