The before after slider is a touch friendly widget that comes with all the necessary features to help you show two versions of an image together.
Favorites are a Member’s Only feature, which you can access right now for FREE simply by creating your own account.
It’s that simple.
Did you see the other "Image - Compare" addons like the
Before After Slider?
p.s. You can find these under the "More Like This" section on each widget/extension page :)
