I have a football news/info website, and I have been looking for a way to get images of the latest matches (the type you get from Getty Images) for free. I haven't found any, and I don't want to buy images because it's only a small site and it's just me running it. Now, I had an idea to take screenshots from the match from when it was shown on TV. Is it okay to use these on my site? Thanks
No, you are not allowed to do that. Any reproduction of matches requires written permission from the agency showing/publishing them.
Only if you own the pictures (took them yourself) or you have permission from the person who did take them.
If you were at the game, you may use the pictures you took, but if you are watching a feed you may not take a screen shot.
I just realized you probably mean UK Football (soccer) and not NFL Football, but I figure it's still worth mentioning that under no circumstances are you allowed to publish photographs, even personal photographs, without written permission from the NFL.
