thumbnail rollover pop up instead of on click?

I'm wondering of there might be any way to change the default process of clicking on a product image thumbnail to bring up the larger image and turn it into a rollover? I personally think viewing lager versions should be a click process, but my boss wants everything simpler/faster for (new internet user) customers, so I have to ask...?

I have some familiarity with Hikashop/Joomla but Hikashop has a very large comprehensive code structure, so if anyone has any suggestions indicating exactly where to implement changing the code to do this (should it be possible) it would be very helpful too!

Thank you for any help!

Actually this does work exactly like I was hoping. What I didn't realize was that if there is only 1 image it doesn't do this, but if there are 2 or more, it let's you preview each image doing a rollover of the tiny thumbnail, and then once clicked on shows an even bigger image.

Sorry for asking a self answering question!
