Logos for "classes"

Hi - we are a theatre school, and like many I'm sure, part of our offering is actual productions of shows, say a summer school "musical in a week" or a more major project that kids can register for.

It would be wonderful to be able to attach a logo/square image or something to "classes" that would show in the online registration etc.. (and while we're at it, more options for configuring the styles of the online registrations pages to fit in wtih custom web designs would be amazing too)
