Giffer does not add a header to the GIF format. What you are seeing is probably the "finderinfo" header that is appended to all Macintosh files. It may also add a resource fork. The actual GIF is kept in the data fork; this is all that you should be concerned with. All Mac file transfer programs (be it ftp or whatever) will add the finder information to any file that is brought over to the Mac; you do not need to do this yourself. Likewise, they'll strip out the finder information and the resource fork when sending files, unless you specifically ask them not to (i.e. MacBinary transfer). / ::::UUCP:::: the_known_world!harvard!andrew.cmu.edu!jg2f+ %\/ Jude Anand George :::BITNET::: jg2f+@ANDREW | jg2f+%andrew@{CMCCVB|CMCCVMA} \/\ endanger judo age ::Internet:: jg2f+@andrew.cmu.edu \ :Compuserve: >INET:jg2f+@andrew.cmu.edu
