I'm wondering if there is a built in way to have a different image for the sidebox of a "Featured Product" versus the product page images.

In the best of cases, the image used in the sidebox would NOT appear as one of the images on the product page itself. Is this possible?

I saw that there is multiple image functionality by appending _small or _medium (others too?) to the image and they will also display on the product page. Perhaps by appending _sidebox to the image name it can be configured to only display in sideboxes.

Sorry if this is has been asked already. Thanks!

p.s.
Using a new install of 1.3.8a and JustHost.com.
