Hover product images

it would be more useful if it automatically identifies the 2nd image

I like this add-on, perhaps in part because it was the first public domain add-on that I downloaded, and I was so impressed by the simple elegance of this shopping cart, done with a single file of under 150 lines. I gave it a 4 instead of a 5 because as a brand new LiteCart user I had a hard time understanding just how to get it to work, that the images needed to be in the product images folder, and that I needed to change the DB prefix from 'lc_' to 'lcxx_' because Softaculous added two extra characters when it does it's auto-install. I found it helpful to turn on clipboard history in Windows settings so I could copy a number of image names at one time, then use the Windows logo key + V to choose and paste the image name from the list.
