Hm I don't think there is a designated place to share your anime Pokemon pictures. :(
If the size of the picture is 600 width by 350 height or smaller, you can put it in your sig and show it off when posting. Click here to read more about signatures.
There's plenty of neat activities to do here. You can discuss all of the Pokemon games, participant in challenges if you can start a new game, learn about battling strategies and duke it out on the Pokemon battle server, discuss the Pokemon tv show, or join a Pokemon club and talk about your favorites, just to name a few other options besides good ol' trading. :) If you ever need to take a break from Pokemon, the voting polls and posting games are fun and laidback sections.
