Show alternate image on hover for non-product page

I'm creating a Menu page in the Blend template (Brine family), and am trying to display an alternate image on hover. I'm wondering if anyone has had luck with code that can do this!

As an alternative, I tried converting the Menu into a product page, which does allow for alternate images on hover, but found Product pages couldn't do the following: - Have an intro / header paragraph - Have separate sections with headers - Display item descriptions on the product page

If I could fix the above I could move forward with the Menu page but think it might be easier to try to add the hover feature onto my existing non-product page.

Any advice appreciated - thanks!
