Hi nexthitwins,
1. goto style tab and you can see background option, click on it, now on right side of the color picker you can see a slider, with that you can control the opacity of background layer, which can reveal background image.
2. Currently, we don’t have option and plan to show light box for image. Indeed, we planned to add this feature on our pro plugin – emage – image hover effects on codecanyon.
Thanks,
Blocksera
