Yeah, sadly there aren't many good galleries out there, it's easier to find pics on tumblr, there are some fan accounts that are very updated. I got Harry's pics from one of those, and linked them to make it easier.
Harry has a lot of recent photoshoots, including pics for his albums, but most of them aren't really ~usable for the banners.
He didn't do Fabulous, his most recent photoshoots were for The Guardian (which is what I linked on 7, 8, 9) and also for Rolling Stones, but those pics aren't good for the banner. :/
