Thanks once again, Rog.
I knew the Gallery was gone, but when |I saw the site I thought maybe there was supposed to be something similar.
BTW, is it safe to delete pictures from the Camera Roll? This doesn't affect Phototream does it? (Done it with a few test photosnbut want to be sure there isn't just a delay like when they upload).
There is a very basic photo gallery in Photo Journal, but it is populated only from iPhoto for iOS, not from a Mac. I can't advise about Camera Roll, not having an iPhone, but I'm sure others can (I should ask separately).
Sample Photo Journal album here.
