This something the RadButton has that I'd like to see in the Toolbar as well
I don't want each toolbar button to have it's own "ImageURL" so I get more resources downloaded.
Instead what I'd like is the ability to say
So the image element for that button would be inserted left or right (depending on the Position set), but have the CssClass applied instead of an image so the css allows me to use a background image sprite.
I know I can probably skirt it by setting CSS to be like "Prev_right" and "Prev_left" but I'd like to make this easier for my devs...the RadButton handles it very elegantly.
