Signature image size limit?

[Set]

I went hunting through the rules but couldn't find anything on this. Is there a height/width limit for signature images that aren't uploaded through the forum? I tried to cram all my birdies into one image and it came up fairly large in height - 420px to be exact - and I don't want to put it up of it's too large.

as long as its no taller than 300px and no wider than 600px i think is correct... ill take a look myself

Edit: couldnt find anything but i think what i stated about is about accurate

I just has to be small enough for it doesn't crowd the whole window up and make it resize. :)
