I have been trying to do research on a program for creating sprites and tiles for Torque Game Builder. I found GraphicsGale which can create sprites and hase onion skin to help with animation. Are there any other programs similar or recommandations? I have tried hand drawing my sprites and putting them on the computer but without any kind of "sprite sheet" they would jump around when I animated them.

Gimp will allow you to preview animations of frames and export animated gifs, but it's not really targeted at making sprites. Personally I prefer to make vector sprites, not pixel/bitmap ones.
