I'd love to use a bigger signature image, but I follow the rules as stated in the Edit Signature dialogue (<= 500x100, 19.5kB).

Yet I've just seen a signature which is 790x527, 220kB.

It's at http: //pornpicer.com/files/5pl2cl6va160ooqt085i.jpg

I want one like that too.

Either the rule has been changed without changing the rule text, or the server software is not very clever. Which is it?
