Personally, I would suggest not using Dreamweaver for anything.

I would search Google.com for thumbnail preview script or something.
I'm search sites like DynamicDrive or javascript.internet.com have
plenty of good examples to steal from. Once you have a basic
idea of what you want to do, and still can't get it to work right,
I would then suggest you to revisit this forum with what you've
come up with so far. This way you'll have learned some, and have
given the impression you tried.

If anything, go to Dreamweaver's help menu and search there
for tutorials or something.
