I see that at least some of the pictures you're using are the ones I took for my website. I imagine it would be a nice feature for users if you'd include a way to import into your app the bitmask produced from the 'share' link (or register as a receiver: clicking that link on Chrome 55 and later on Android will open the native sharing dialog) and be able to export the same link back out.
Also, just FYI, there's another Android app and someone was working on an iOS app a few months ago but I don't think it ever materialized.
