Episerver doesn't come with this type of adavanced visual controls, but you can check on https://www.coderesort.com/p/epicode/wiki/WikiStart and search for "image gallery" and you might find something useful.
EPiImage is nice!
You will have to make your own code for comments(using dds).
For comments you can either create your own (using dynamic data store as storage for instance), or better use something that works great: Disqus for instance.
Hope this helps.
Thanks a lot guys!
If you see this sample here from zdnet, there's an image gallery with navigation buttons. Below it, there's also a comments section. Do we have something similar like this in EPiServer, or do we need to build this one?
