Hi,

e.g., please see

http://groups.google.de/group/comp.soft-sys.math.mathematica/browse_thread/thread/43081cda374c5075/a4cff025b44a7beb?lnk=gst&q=gif.exe#a4cff025b44a7beb

GIF.exe is the compiled mathlink exe Mathematica uses to export an
image as GIF; it is one of the Mathematica system binaries folder.

Best regards, Andreas
