It’s not where the photo is taken, but on which website it appears, when considering copyright. And please note that transferring it to Photobucket doesn’t make a difference.
Thanks for your comments. Yes, I was aware of that. And I am astute enough to realize that posting it at Photobucket doesn’t change its legal status. Another thing that I became aware of that has changed my posting habits is not posting images taken from videos that appear at the article. I’ve been doing that for a very long time as a way of enhancing the post, never thought of it as a copyright issue, but then last week, when the picture of a video I posted was removed, I realized that an image of a copyrighted video is copyrighted as well, and so stopped that practice.
Thanks again for your comments.
