In Clovemix free version, I got the homepage boxes to show such images as I had set to be the “featured images” of the pages that each box was linked to.
BTW, what is the optimal size to make those images? I settled on square 400 x 400.
When I upgraded to Clovemix PRO, those images were not showing, but adding or removing them from pages did seem to affect the layout positioning. I was probably in Firefox or Safari on a MAC.
Then I tried it on Win Firefox and it was also not working, but Win Chrome was working.
Today I went to collect information, and it is working on Win Chrome and Firefox, and is working on MAC Safari and Firefox, but not on the MAC Chrome: missing those images.
