I've limited signature sizes to 290px (height) as they were becoming quite a problem, so much so that you actually focused on the signature more than you focused on the content of the post. If your signature is higher than 290px, then the remaining content after the 290px just gets hidden automatically. If you don't know how to resize images, MyBB can actually do it for you. Code: [img=200x100]img link[/img] That would resize the image to 200x100, it's that simple. As long as you don't make it higher than 290px (including text) then it's fine. If this is a little strict or perhaps too lenient still then suggest alternative size limitations here.
