I'm quite new to this forum as you can see so I'm not quite sure where to post this question. I've seen a lot of people having small pictures/animations of pokemon in their sig, so my question where do you find them? And where should I post this question?
You mean .gif images? Most people usually find them on sites like Tumblr or in the case of the Pokemon sprites, it's sites like Pokecheck and also lately PkParaiso for the XY models (the latter is in Spanish though). So yeah, loads of places where you can find these sorts of things!
