On one of the Stack Exchanges I frequent, an Asker included a link in the Question to a photo on the web site of a newspaper. Later, someone else (with the best of intentions, I am sure) edited the Q to convert that hyperlink to an Imgur uploaded image.
I flagged this as possible violation of copyright on a protected image. A couple days later, the flag was closed as "helpful" but the image still displays in the Q.
I have found two prior "related" posts, Clarifying fair use regarding a Stack Exchange site and an imgur hosted image and imgur, copyrighted images from the web, and imgur accounts, but neither answers my question.
If, as I strongly suspect, the photo is subject to copyright protection, then changing the hyperlink pointing to the image, to an embed of the copied and uploaded (to Imgur) image, may violate that copyright. If so, is it o.k. for Stackexchange to allow such a violation?
And a follow-up question: Would it perhaps be simpler to switch SE's image hoster to Wikimedia Commons, which has a very strict policy on copyright and many volunteers combing through the site every day to weed out violating uploads?
