I have purchased Fresco for use on a client's site and both of us are extremely happy with it's abilities and performance.
We are in need of adding an image comparison/difference feature, if at all possible. For example, something like this:http://zurb.com/playground/twentytwenty
He has the perfect use case for displaying before/after photos and it would be perfect if this functionality could be adapted to Fresco. If there any way to make this happen? I would be more than happy to pay for the work involved by either a member of the community or by the creator of Fresco.
Would really appreciate further information/comments.
