Question
For example, I see http://www.historyoftheworldcup.com/credits where they have listed all credits for using pictures. I think I need to seek permission from all the original owners of assets, before using these on my website? Is that right? Are there any standard policies for sports' events pictures?
Answer
It would be better if you asked permission before doing so. The historyoftheworldcup site probably was able to get the right to display the image with credit by asking the original photographer. I would recommend you do the same. You can run into serious infringement issues not to mention the fees that may come with the infringement claim.
