what do you mean?
as in, sprites? images? banners?
Did you look?
Can i have a signature 440X80
can it have Groudon and kyogre fighting.
On one side can it be red(groudons side) and the other blue(kyogres side)
and then can it have really cool steel like text saying Pokemon Blast Ruby & Crush saphire
Sorta wrong section.
Anyways there is the Graphic Request Thread, where you can request signitures/Avatars/sprites (though I doubt they get this)/ and yeah.
But not everyone gets something made in there.
In the graphics & photography section there are some shops. now dont go willy nily. they probally will have a [Shop] section.
So yeah LOTS of people make signitures. But if you want a signiture with css, theres no place for that, your on your own.
