Ah, the ol' empirical method. I know it well. :-)

In my experience with GIF (IDL pre 5.5) PNG, JPG, TIFF, EPS, I've had
no problems Mac/Linux/Windows. Make sure if you're using an older FTP
program, to transfer the files with "binary" on. "sftp" from the OS X
command line seems to either always use binary or never have a problem
interpreting which is which.
For other IDL binary files, like variables saved with the "SAVE" and
brought back with "RESTORE" commands, you will notice a byteshift
going from Intel/AMD to Motorola. For those files, I often have to
test the different byte-swapping keywords until one of them works.
Fortunately, once you guess the right one, you know it forevermore.
