To the right or left of this answer box, or however you so choose, add a box with a search bar.
In the search bar you type "Mewtwo", and right under pops up a Mewtwo sprite. That way, we just copy it straight from their instead of going back & forth between sites. If you can, could the sprites be animated because no doubt those are more popular than static ones.
It would just make adding sprites easier, and sprites IMO are essential because it can make the walls of texts that are RMTs easier to read.
