I've never worked directly with the radiobutton list, so how it would be done excatly I can't say.

But you can place images at radiobuttons by for instance providing the html image source code in the text value. This way you'll get an image next to the "button" (Perhaps, this could be done by adding a image control to the radiobuttons control).
Such as: RadioButton.text = "<img src="someurl" attributes />"

And I would suppose the RadioButtonList can bind to a collection of radiobuttons, so I would say - it is quite possible.

If this isn't what you request, then I don't think I understood your question right :/


Hope this can help you on the way.
