Miss I'm very sorry but you did. Your statement that it 'obviously' had no copyright. Is incorrect but yo be fair to you a common belief. All photos have a copywrite, including your own. Seriously I mean that, you have copywriter on your photos. That's why when the fail/other tabloids use celebrity Instagram posts to illustrate stories you'll see for instance in this case C Anthony Joshua/Instagram (facebook/twitter) it's Anthony Joshua/press photographers photo. It is not yours you have not been given permission to use it. You stole it. Unless you asked the person who took it be Anthony Joshua or a member of his family, permission to post it you broke copywrite.
Hay I've got a few pictures of my sort of celeb totally not celebrity crush on my phone, I'm fully aware I'm 'stealing' them though, my friends even go oh naught will nab that one! So every one does it your right, doesn't mean that what you've said is true.
People can get in to a lot, and I mean a lot of trouble for posting pictures that they don't have permission for, a charity one of my colleagues used to work for got charged £5,000 for posting one of those pictures you just down load of the internet, by which I'm guessing you mean from Google images. I know of a case where a celebrity said very clearly that some press photos for an upcoming production were for his official website only, and a 'fan' decided to screen cap them and post them on another fans forum, the production company started legal proceedings against both the celebrity and the fan who owned the forum, not even the person that had posted them.
At work I have to be very very careful about what pictures I can use. my job relies on pictorial images I produce information for people with learning disabilities. I have to go to search tools and labelled for reuse.
I'm not saying this to get at you, many people are massively unaware of the consequences of posting photos they just down load from the internet. But it doesn't give you the right to get angry.
