how does raw image data get you anything? Seems you want the data and the image URL via XHR and then dynamically insert your DOM bits (img tag w/ URL from response with some sort of wrapper containing your legend)... I mean, what you are talking about is technically doable (not in all browsers) http://www.kryogenix.org/days/2003/10/18/embedding but I am not sure it gets you anything.
