There are some HMTL tags this widget doesn't like...it’s a bit of trial and error...if you have an external server, you should be able to call in the image or create an iFrame. Also check her HTML & CSS discussion board...others may have achieved this.

Are you trying to do like image mapping links? Another way around in that scenario is to essentially segment the image into pieces and just stack them with links instead of doing the background image, but only works in that scenario.
