I would like to propose that we increase the signature size limit to 500x100. I don't see this as being a problem because it will not add any height to the image.
SO PLEASE, PLEASE, PLEASE CAN WE DO THIS?
Just think of the possibilities one could do with that extra space! Especially for those who like graphic design, like myself. =p I know this would never go through but, after playing around with different sizes, I personally would prefer 500x125. It is not that much taller/higher and you can make some awesome stuff with that size.
BUT, I am shooting for just adding the extra 100 pixels (in width) if that's all I can get. I know all you picky peoples wouldn't like the extra height. 
But it doesn't hurt to ask/mention it, right? 
However, I do understand the problem in adding height, "because people already have like 200 pixels worth of text in their signatures." And speaking of text, I think we should reduce our character limit (for signatures) to half of what it is now (which is 1000). The Soda Shop only allows 255 characters. Besides, who needs 1000 characters anyways!
Below are samples I made featuring both 500x100 and 500x125. Don't knock it till you try it, peoples.

With our current size it makes it harder to find pictures that will look good and not be stretched or disfigured.

Because I remember discussing it; I thought it was implanted...
Oh, those days.
