It would need to be modified a bit to find/replace the images in the sig code, but, it's a start.

Since sigs contain more than an image, you'd need regexps to find the pics.
Also, $sig_URL[0] and $sig_URL[1] should be $sig_dim[0] and $sig_dim[1]
Besides that, calculation seems unnecessary - just check if either width or height is higher than it's supposed to be. A 1*7200 image would then also be killed
