Resizing frames for back sprites

[Boeing747]

I'm trying to unify the trainer backsprites so that they fit the Pokemon Black/White style, but I'm having trouble with the throwing animation. My frames are 144 pixels wide and 248 high; the whole picture is 720 pixels wide. When the player throws the ball, instead of showing each of the 5 frames, it shows a cut image of the sprite sheet.

I don't know where to go to fix the frame sizes in the script.

I'm really sorry if this sounds super-asinine, even for the things I've been asking.

The trainer backsprite file's frames must be square, but may be any size. The whole graphic can have any number of frames in it, but the animation currently only supports either 1 (static) or 5 (1 static plus 4 throwing) frames. Any additional frames are unused by default.
