Some examples:
[wowsig]53247[/wowsig]
[wowsig]412325[/wowsig]
[wowsig]214317[/wowsig]
to use it: [ wowsig] #id [ /wowsig], you must be premium to have the sig image work, anyone can view it.
You can use these sig images from any site you like.
Just testing at the moment, the image location will change once I work out a couple more bugs.
