You can go to Theme Options > Products Page Layout > Product Image Hover and change it.
Maybe some additional plugins could implement some other hover effect but we can’t guarantee full compatibility with third-party plugins.
Yes, hover effect with description and slider effect works fine, but tooltip and swap do not work. I do not know what swap does also. Is there a way to feature image of the product have effect of changed image from gallery or anything else?
I used ID shortcode to call product on my homepage. I set now swap for you to see.
