I'm wondering what is allowed to do with editorial images (as opposed to "commercial" photos) - and I'm not talking about the rules of a specific stock photo agency, rather about laws.
I know commercial photos can be used for commercial purposes and editorial purposes, thus I can use such a photo vor promoting a product (advertisement).
As far as I know, editorial images must not be used for commercial purposes, to promote something/advertise for something because it may contain object and/or persons without release.
Further most agencies also add (to further clarify) that you cannot use editorial photos to sell anything.
So far so good, but the devil is in the details, because "sell anything" isn't very specific.
I'm pretty sure that editorial images can be used in a free informational newsletter when used in a editorial context (to aid the story).
But can editorial photos also be used in a news paper? When the news paper is free and the photo is used in an editorial context, I'm pretty sure this is possible. But what is with news papers that must be bought (but the photo is also used in an editorial context)? The news paper is sold... so is this a no-go for editorial? Or is this OK, as the editorial images is merely an aid for an article inside the news paper?
Furthermore, what about products. For example if there is an mobile app which uses an editorial images and the app must be bought. I guess this is only OK as long as the image is also only used in an editorial context inside the app. Maybe as an example if there is an app about "Beaches" which describes different beaches and also shows an image of each beach, there could an editorial image of that beach be used. Correct?
