Hey, 

I'm trying to add a hover effect on my banners to change to another image. 

Here is an example from another site. https://www.tobk.co/ if you scroll down you can see the hover effect where it changes to a secondary image which is a gif. We want to do the same but for our banner images on an index page. See J1S.com/work

Any thoughts on how to make this happen?
