[ For avoidance of doubt: I don't think there's any particular significance to the specific question and edit I've linked to here. It's not intended as criticism of the actions of any one person at all; this has been on my mind for a while and these were just the ones I saw which kicked me into writing a meta post ]

We not uncommonly see questions which have the relevant image linked to an external source (see for example [How to show great heights and depths without the road dividing the picture into two halves?](https://photo.stackexchange.com/questions/72214/how-to-show-great-heights-and-depths-without-the-road-dividing-the-picture-into)). Every now and then, an edit is suggested to the question which embeds the external image into the question (for example, [this edit](https://photo.stackexchange.com/review/suggested-edits/35257)). Should this kind of edit be rejected?
