I was trying to upload pictures to both Imgur and Reddit. In both cases, when I accessed the "Recent" album, the apps would only allow me to pick from pictures I'd taken with my phone. The pictures that I had downloaded into my camera roll (from Dropbox) weren't available. If I go into photos, all of the pictures are there inline with my camera pictures, but they're not available from the apps. I would guess this has something to do with all of the permission I have to give every app now that wants to access my photos maybe? Going through the Photos permissions, the apps have access to "all photos" so I should be good?
