GIFs not working?

[PTGigi]

Okay, so I had about 250 images to upload and I was not in the mood to individually upload each one via the Admin CP. So using my FTP client I uploaded all of these images to their correct folders (PNGs to the PNG folder and GIFs to the GIF folder). Later I went back through and made entries for them in the prefix_filesmap table.

Now I'm trying to code a PokeDex which is going 100% according to plan excluding one thing, my GIF images do not show. Now I am not using the 'getimage' function, I am making a link via a variable $image1 I defined from the MySQL database table prefix_pokedex. Now I know that is not the problem because everything else displays fine. My PNG image works but my two GIFs are not.

So I tried variations of this filepath:
mm2plus.com/picuploads/gif/MewtwoCD.gif
http://www.mm2plus.com/picuploads/gif/MewtwoCD.gif
/picuploads/gif/MewtwoCD.gif

etc...

And none work. Finally I just entered the image url into my address bar and got this:

Internal Server Error

So yeah...Anyone know why my GIFs are failing me? O.o

EDIT: My folder permissions are set to 777 just fyi (I just checked)
