Hey Thomas,
Thank you for your reply. I checked the information in the link you provided, but I`m looking for something different. What I need, is a before/after viewer to compare and show two images, one before the processing and one after. The Avada-Theme got this function integrated: https://avada.theme-fusion.com/before-after-image/

There are many plugins on Codecanyon, and I was hoping someone has already this kind of plugin in use and can recommend which one to buy and to use with the Enfold-Theme.

Thanks again,
Thomas
