@Clay Death to fix your signature, simply add the command [noparse] in between the [img] command and the image URL.
In your case it should look like this:
[IMG][noparse]http: //i1322.photobucket.com/albums/u572/spartacus120/come%20september/my%20super%20sig-2_zpskqftpwvo.jpg[noparse][IMG]
(just add the / symbol to the latter [noparse] and [IMG] commands and remove the space between : and / after the http)
