Image Size

Can you please add width and height to the subfields when you're adding an image to a form? For example, one of the images I'm going to be using is 300x350 ( http://a1128.g.akamai.net/7/1128/497/0001/www.proflowers.com/prodimg/MSOpurblushbqt_l.jpg ) and I'd much rather shrink it at LEAST in half.
