Not sure if feature is the right place for this, so please shift as appropriate mods…
So, I'm getting ready to ship a major overhaul of our product in the next few weeks and we've done a lot of work on the look and feel of the app.
Some of it, however, is a bit subtle so I’d love to include some “before and after” images in the release notes when I post them.
Ideally, it would be something like what’s shown here, where readers can slide back and forth to easily see the changes.
I am not particularly technical but I do have a few developers at my disposal. For the moment they are all heads down finishing the release, obviously 
so I thought I’d ask if anyone has any ideas about how I might achieve this.
Any and all advice would be appreciated – thanks in advance!
