I used to mod at a forum where we regulated signatures that were way too big/spammy. You know, I'm all for text, and graphics that are used tastefully and in respect to other members, but when the image starts exceeding 500 px length-wise it just becomes a burden, especially when multiple huge pics are stacked right on top of eachother. In all regards, the same images can be used, just simply scaled down to a more proper and friendly (to other members) size.

I totally agree. Nice, small, and to the point.
