I have a potential client that needs a way to have his customers create images from a drag-and-drop interface that will allow them to save the image. For example, the customer selects from an array of backgrounds, clip art and text and they can move these elements around and then save it.

I'm trying to find a plugin I can license, either Flash or HTML5/jQuery that has such functionality. Any suggestions?

ps - I had an example of just the type of plugin I need but as a new user I'm not allowed to post the url to it.
