I used to manually optimize the colors in images, but that's a long and tedious process. I've heard of batch converting, and although I can do it with IrfanView and PSP7, it does not do it well enough, since it changes the colors, including transparent pink. Is there a batch converter out there that anybody's using that can lower the color resolution on images and use an optimized octree palette? If so, can you tell me the name of it?
