Many of those images look the same. I know nothing about this game but I would personally put all the Pokemon face icons on their own sprite sheet (under the "Miscellaneous" section) with a background color and a small credit tag (like "ripped by gamer5020"). That would get one thing out of the way.
For more about sprite sheets, you can look here. Instead of uploading whole screenshots, you should cut out the parts you want from the screenshots, like the Pokemon pictures, for example, then you could put all of those on their own sheet, or if there were sprites of Mario, you would have all his sprites on its own sheet. If you wanted to rip the text in the game, that would also go on its own sheet. That's how we do things. If you need help with anything else, then I'll try my best to assist.
