Is there a way to export/share "favourite" gallery images? I have selected a few hundred images as "favourite" in the stock Galaxy S3 Photo Gallery app. I can view these photos by tapping on the "Albums" drop down and choosing "Favourites". Once in this view I can open individual images or start a slideshow. There is no multi-select option like in "albums" view which allows for bulk sharing of images.

Does anybody know a novel way to export/share all favourite images? 

I have tried other gallery apps in the hope they shared the "favourite" database but each has their own. AirDroid also does not have a "show favourites" option. 

Or does anybody know if the list of favourite images can be exported from some sqlite database and I can script out the file names for copying? 

Thanks!
You need to use the Photos app instead (it no longer requires a Google+ profile) which has the option you are looking for in the latest 2018 version. But you cannot export or migrate your favorites out of Gallery and the Gallery app is removed by Lollipop.
