Signature link not working!

Well I got some1 to make me this epic signature and the link for it works fine on mmoexchange and other sites but it doesn't work here.

When I try to put the link up in the option 1: link for signature, it says its an invalid file.

It also was the idea of when you click on the sig you would go to my vouches page.

Any tips on how to fix this?

The link is

[img width=500 height=150]http://i56.tinypic.com/10gfd3b.gif[/img]

 

PHP:

[url="vouches Url"][img]url To Image[/img][/url]

 

thanks man! much appreciated!
