Double Combo Box Produces Images?

[kvarnerexpress 0]

I am trying to do a website which requires two drop down boxes that will display different images. Basically you select a category then you can select a sub category from the second drop down box.Now all the scripts I found online that do this direct you to a link by either pressing Go or some kind of submit button.Can some one point me in the right direction to make the selection show different images?In the end I want to have an image show up when you select the sub category, then have the user be able to drag and drop that image to a different part of the screen.I have a drag and drop script that I can use, but I can't find a double combo box that will display a different image each time and not replace that image when a different category is selected.Overall the user will create his or her own bike, so they need to be able to drag and drop and the images have to stay on the screen so at the end they can see their completed bike.Any help at all in this matter would be greatly appreciated.

Sounds like you'd probably need AJAX.
