The problem with using Pokemon Elite for your images, is of course, that putting too many of them in your sig means your sig is breaking the rules. Isn't that right JONNO.FRESH?
Alternativly, use this link: http://www.serebii.net/torouze/pokemon/010.png and just swap the numbers at the end for the pokemon you want. Then, since the images are coming directly from Serebii.net itself, you can put up to 8 in your sig without fear of it getting deleted.
