I’ve never used it, but isn’t the CM Snap camera app free software and has a gallery/edit function? I never looked into CM myself, but I read someone here used it and liked it. But maybe I’m confusing things … but if someone wants to check? Testing CM is always a bit complicated, often there are lot’s (unnecessary) dependencies. So I haven’t checked, so maybe I’m wrong.
Here is the post. @m4lvin Can you tell us if Snap has a working gallery with crop & stuff? Thanks!
