Images in drop down selection list

I've exhausted my searches to find a way of using images in a drop down selection list in an HTML form. In essence dynamic thumbnails. I build a drop down selection list from files within a folder. I use an array to store the file names for the drop down list. It functions fine with the file name text but I want to add the associated file name image or replace the text with the image altogether, like a thumbnail. Any ideas? Thanks.

That's an interesting idea.

Here's what I found that should work for you:

I think you'll be pleasantly surprised. I'm assuming that you are programming in ASP.NET.

Thanks A O, this has potential, I'll let you know how it spins. I'm currently messing with some Javascript and managed to get the images into the dropdown list with a floating id but not working with a selection function.
