That's not a bad idea. I once had a magazine misuse some of my photos because they didn't understand that the Creative Commons license I had chosen, (Attribution, Noncommercial, No Derivative Works), didn't actually mean 'take it and do what you want with it' like they thought it did.
You might want to also consider linking to the peoples site/flickr page etc so if anyone else wants to use the pic, or even just view more of their work, they can go straight to the source. I just tried to find one of the pics cited in an article and the flickr username provided was a bit too generic to easily search for it.
That photo credit line should be a lot smaller really. It is almost as "in your face" as the title.
@Rallier: See, I really like the huge text. I think credit gets 'hidden' more often than not when other's content is used on news sites. There's something instantly appreciable to me about the huge bold text saying where the picture came from: something that says Tested understands journalistic/editorial integrity to the point where they want to be sure everyone knows where the content comes from.
It probably doesn't have to be so big. I've seen plenty of sites that provide more information, (type of CC license, link etc), without being so in your face. But it is a nice ego boost to suddenly see your traffic go up and track it back to find your work is being used. But that only happens when a link back to my page is provided. And isn't a requirement of the CC license, just the other person being nice.
Personally when people have used my pics I've always been happy if they simply provided my name and a link back to the flickr page it's from. The license is listed on that page so there is no confusion.
I know this might lead to an excessive amount of coding for a small feature but it would be cool if it had a simple expandable element (like the spoiler tag in GB) where it gave all this extra info and a link back to the user page/direct link to picture.
Adding options to cite specific CC licenses with photos is on the list. We also need to add links.
