How to activate hover for a second image in non-product pictures?

Hello,

I have 2 questions that I would appreciate feedback on:

-I know that you can activate “Hover for a second image” for a product listing. How would I activate this feature for an image that is not a product?

-I have inserted images in each column of the Multicolumn section. How can I embed hyperlinks in each of these images?

Thank you and wishing you all the best
