It needs to be in a tag, so I can parse it out easily. That's why I went 
for an img tag, as the original person who wanted the feature was going 
to use. If you can suggest an additional attribute of a tag it could go 
into, I could probably implement that as well. But be warned that all 
these things slow it all down even further :-(
