Drawing tool

I need to create a form users can use to email product specifications with. If it was just a bunch of textboxes, it'd be no problem. But, in addition to some text info, I need them to be able to include a drawing of the layout of the products. Of course, simply uploading a drawing they made on their computer isn't an option, so I'm looking for a Flash, Java, JavaScript, SVG, or pretty much any other client-side technology solution.

The products are pretty standardized, so instead of sketching each one, a list of clipart images to drag and drop would probably be best. The drawing should be sent as an image (bitmap, jpeg, gif, png, whatever), so the app needs a way to save the sketch.

Anybody heard of any commercial products that satisify this? Even if it's not a complete solution and I need to change some code, that's fine. I'm just hoping to save myself a lot of development time.

I had seen something like this somehwere else but I couldn't rember where it was, but a quick check of hotscripts.com led me to a couple possibilities in java (I think you'll need java or flash for this most likely java if you want to drag and drop external images) http://www.hotscripts.com/Java/Applets/Image_Effects/Image_Editing/index.html

you definately might need to tweak the code but these might be a start.
