Hi all, I would like to share here a simple python app I'm coding: PicPacker. It's -or will be someday- somehow similar to TexturePacker. It takes same sized images, processes them and yield, as you all has supposed, a single image containing all the others. Also if you specify it you can generate a json to index all images.
If you like be my guess and try it, at least for testing purposes ☺️
