Attribute image swap quetsion

I'd like to have an area to the right of my drop down attribute change when the attribute is changed. The attribute type is a drop down. The site is nowhere done, so please forgive the incompleteness of it.

www.hardwoodcanes.com

The product I'm looking at modifying is:
http://www.hardwoodcanes.com/walking-cane-with-snake-head-p-3.html

The attribute is "Select wood type".

I'd like a window to the right of the attribute, about 200px wide by 100px tall to change images per the image that I have set to that attribute option value.

Maybe this has already been covered by another thread??

Thank you.

I haven't tried it myself, but this seems to be what you're looking for: http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=994

Thank you for the reply. Unfortunately, that add on won't work, as it looks like it replaces the main image. I just want the image to popup to the right of the attribute switch.

Ah, ok there seems to be a module for that too: http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=616
