This is undoubtedly related to the issues in other threads below (i.e., a partially screwed up database) but I haven't seen this mentioned so I'll mention it here.
One of the photographers in my "favourite" list supposedly posted a photo today.
"That's odd", I thought, "I've never known Bill to post nudes before".
And sure enough, he hadn't. That particular image linked through to a completely different photographer's gallery.
However that photographer's gallery has the same name as Bill's PAD gallery, and when I click on the "Galleries" link, it goes to Bill's galleries rather than to the nude photographer' s ones.
When I look at Bill's PAD gallery, I see 4 different photos from the nude photographer. So clearly, these have ended up loaded to the wrong gallery. Or, in database terms, are linked to the wrong gallery.
I think it's safe to say that something is broken in a major way.
