Finally time to join the discussion
I need to say, as a photographer, albums is a must have! And some kind of efficient tagging system would make the whole thing even better. To not only come with demands I would like to suggest a, at least temporary, solution as well.
I would suggest implementing an album into the user profile and then link to a photo, or album, in the according post. It would be cool to be able to link likes and comments to photos/albums but I don’t really know how this should be done. Then I would not sync photos between pods but rather, as it is done now, hotlink them. This is both more efficient and gives the user better control over her/his data.
I would like to give some attention to the openphoto project as I see their software as a solution for our albums. They support comments, likes and do even have a tag system. I think you can also release albums to a limited group, this could be paired with Diasporas aspects. It would be cool if someone with more coding skills would look into this and check whether it’s possible for us to use that software or not!
http://theopenphotoproject.org/ and of course it’s open source.
Hope we can use this or similar software. That would decrease our work and speed up the process of implementing albums.
