There are a lot of solutions as forum readers, the problem is the image upload for PP, that it seems it will never happen here. VB
mobile solution works perfect, you can create albums and upload photos directly from the iPhone, but the pictures go into the user albums, not in PP.
So just have a tab to see the gallery and not being able to do anything has no sense, they can just get in Safari and do the same...
PP should give a solution for this, like having the user albums from VB
forum into the user gallery as mobile album.
That way users can upload photos to the forum album and will appear as another album in PP.
Just pray to something like this happen and PP does something, if not, well, stay with no updates and nothing new in your gallery.
