Most of it applies to photosharing websites as well - especially the bit about keeping the title/headline below the image. I'm irritated every time the title is at the top and I need to scroll up to see the title (The initial response for me is to inspect the photo - exactly as mentioned in the article).

Building one myself, I instinctively felt this should be below the image, but my designer disagreed and that's the way it is right now. We will definitely push this down - evidence always wins :)
