You could use some of the string-functionality to clip off everything until
the "." in the filename. Note that you can't just clip to the last 3, as
some might save with "JPEG" instead of plain, 3-digit "JPG". Then again, you
could tell that someone did that if the remaining 3 digits showed "PEG"...

Anyways, once you have the last three digits, use
strcmp(One_String,Another_String) and check if they're equal (if they are,
strcmp returns the value 0). Use the proper format according to the results.
(e.g. #if (strcmp(TestThis,"png")) png #end).

Of course, this won't work when somebody doesn't supply an ending for their
images, but shame on those that do that! :-)
