Try that one.
The one on the first post has a tranparent background so it can be put over any background colour (although you need a program that supports PNG transparency...), but if you're using a white background it doesn't matter.
Presumably on the random banter or SMBG subforums? That's a possibility, although it might be wize to ask a mod first, since it would technically be a duplicate thread.
That could be a good idea, though, as we could keep this and other threads purely for posting and archiving work or directly related comments.
Another possiblility is moving this and future threads to the Arts and Crafts boards, assuming their more lenient about off-topicness over there, which I may be completely wrong about.
