Looking at this whole thing logically, I'm thinking:
Since this appears in your source:
<!--bof Additional Product Images -->
<!--eof Additional Product Images -->
the template file is OK.
Since the images don't appear, despite the template file's attempt to display them, the problem pretty much has to be that the images aren't in the place Zencart is looking for them, or aren't named properly. I can't think of any other cause.
Update: I added an additional image to the product in the demo Music category, naming it sooty_01.jpg (the original image is sooty.jpg). It displayed fine. I then changed the file name to sooty_01.JPG (uppercase extension) - didn't display.
Hmm, interesting - I originally had an uppercase extension on them. However they are now in lowercase and still not working :(
DivaVocals:
Not really.. if your template doesn't have this file, then Zen Cart will use the one in the default_template.. You would only have this file in your template folder if you had modified it. (AKA an override)
I would suggest uploading a CLEAN default_template folder to your site via FTP.. Perhaps the default version is corrupted..
Ok, I'll give this a go tonight.

Can you just make the image called red.jpg and then red2.jpg, and don't worry about the MED and LGE suffixes for the moment.
Ok, I'm back to just red.jpg and red2.jpg now. Both files are under 50kb.
