Drag and drop photos from drop down menu

I'm trying to get a drop menu that when selected shows a preview of a picture that can be dragged to another part of page. I have a script for a picture drop menu and one for drag and drop but i can't get them to work together. Can anyone tell me how to get them to work together or tell me where to find a script to do it. Thanx
