sN0wBaLL made the Psypoke TC's. You need 25 posts and 25 Psybucks to get one, but theyre currently not available because psybucks aren't fully functional yet. However, http://www.pokecharms.com
can make them in a few minutes, or you could try Sunyshore Market. :)
To rank up from Bug Catcher you need 25 posts. A list of ranks is in the FAQ, but they could be the old ranks.
Edit: Misread your post. If you've made one already, just upload it to photobucket.com or imageshack.us. Then use the IMG code provided.
