See this question: UML Class Diagram for an E-commerce webSite?
(At the writing of this question the OP has 11 rep, so now he can add images, but he couldn't before he got to 10 rep)
If you look at the question's edits, the OP had two links to the UML diagrams originally, then another user turned them into images because he had the rights.
BUT then the OP wanted to make an update to his question, he couldn't due to the images!
So as a new user he did as any sensible person would do. He thought of a solution and posted a new answer with his update.
Then an admin admonished him for doing that and updated the post accordingly, deleting the comments.
Why did this need to be done?
Why can't the OP edit his/her question when the images were added by another user?
Can we change it so that if another user adds images to an OPs post, any edit is allowed to have those images (and not any new ones)?
