Hi, is it possible to make zoom enable, only when you click on main product image and not be enable when mouse roll over?

Hi,

With current states (without coding edits) "NO", that's not possible. But this is a 100% custom modification and unfortunately we don't provide free support or step-by-step instructions for custom coding modifications.

You may purchase premium support:

and let us take care this modification for you directly on your website though.

Regards.
