Hi- I found this old thread: http://lists.freedesktop.org/archives/create/2009-February/001578.html That talks about tagging. I've also looked at the source, and am not able to locate how the checksum is calculated. It does not appear to be a md5sum of the actual resource file. How is it calculated? -Rob A> _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
