Need interface for direct user download of images (no right clicking)

[Teri]

Does anyone know how to code a thumbnail image (or text link) so that when the user clicks on it they can directly download the large image to save on their computer. I would like to avoid having to put "right click and save image as" instructions on the page.

Thanks!
Teri
