There's no law against fake news specifically, just damages to reputation as a result of false claims. The legality of individual photos varies greatly, but overall most of the photos are legal as evidenced by the lack of successful lawsuits on the topic. Lawsuits are easier when you're talking about millionaire/billionaire celebrities.
I wasn't disagreeing with the point, I just felt the urge to be nitpicky and point out that the given example doesn't prove anything.
The same excuse the magazines use for the articles would be just as applicable with these pictures, as we thought it was legit transfers directly over to we thought they'd given permission.
It's all fine legally as long as the articles are retracted for missinformation
What you're thinking of is getting damages/convictions because of the misinformation. That's indeed quiet hard and will require proving that you've actually been harmed, which is extremely challenging, generally speaking.
