Im using wavelenght and going to make a sprite with multi frames. But when I'm going to load the second pitcure I get the error that they not sharing the same palet... I have saved them in 8bits BMP files. but what can I do to get them use the same palet?

1. Take all of the original frames (preferably in 24-bit color)
2. Combine them into a single image (just loosely, no need to arrange the frames perfectly)
3. Create a palette from that resulting image, and save the palette
4. Reconvert the original frames to 8-bit color, using the new palette
