Not to get this into a debate of legalistic triviality. But, since we have some comptetent lawyers who read this site, I would like some of them to weigh in on this copyright issue. If one uses a jpeg from another website, even if the photo has a sub-caption that states it is a copyright photo, can it be posted in a not-for-profit web page discussion forum, where people are merely looking at it for discussion purposes?
Or to refine this, when one uses the copy and paste the website url of a jpeg photo from a place like Google Images, even if it says copyright somewhere in the web page or source that Google Images got it from; can it be posted for discussion purposes here, since there is no money or financial remuneration being had by the poster using the photo to illustrate a discussion point of view?
I suspect there is no requirement at all, and at the worst a mere note below the photo saying, this photo taken by......
Now, if one were reselling or making some financial gain out of posting the photo, I can understand that is a very different story. Such would be writing a book for sale, and using a copyright photo. Of course that is understandable.
Maybe Aiden Bradley might weigh in on this question.
