Unable To Set Signature Image

[Phonantiphon]

Hi,


I'm having a problem where I am trying to post an image to my signature.


I'm direct linking it from Imgur, and the image is 262 x 200.


I can attach it, but when I click to save the signature, it won't actually save it and it comes back and tells me that I have to abide by the image sizing of 836 x 271. But the image is 262 x 200!


This is the image: 


I can't understand what I'm doing wrong, if indeed I am doing anything wrong...?


Any advice == gratefully recieved!! 


Thank you.


Ok, well that's weird, because although it's told me I can't, it clearly has...!
