Well, I have no idea how to use it, but do see you are using HTML with the <>. You do need to use UBB img tags, with [] as they turned off the HTML some months back. If you see somebody using it in their signature, maybe send them a PM and ask.
You can see here if I use the [] I can get an image, though out of date. Go to the quote icon in this post in the lower right and you can see how the code looks.
