You might also want to play around with the ListView, which is better designed for using pictures as items, but doesn't have the drop-down functionality inherently. If you are willing to settle for scrolling, then the ListView will handle the images directly (though the ListView is such a strangely versatile control that it has a bewildering assortment of settings...the key one for you is Mode = Details, or something close to that). To cause that to act as a dropdown would be a bit odd, but I would suggest that it be a ListView showing images with a button to the right of it showing a down arrow. When you click the down arrow you would expand the size of the Listview from 1 item in height to N items in height (based on the amount of room you have). You'd also have to get the scrolling right so that when it expanded to N items, the item that was being displayed at 1 item height because the top item, or the selected item, or whatever else looks best. It would be a bit weird.
