I have edited a lot of posts on Stack Overflow where all I have needed to do was add in images. The user gives the link to an image, either because he is unaware of the in-question image ability, or he doesn't have enough rep. So I am proposing that if the only edit that is done to a question is adding in those images, we could just let the edit pass through the system without checking it, instead of wasting the edit patrol's time.
Once a user has enough reputation (2000) it is possible to directly edit a post. At that point that person is considered trusted enough by the community to directly edit posts in a way which adds quality to the content.
Presumably the reason that edits are required to be approved for those under 2000 reputation was from low quality edits. I feel that images are a place where this request could really be exploited.
It would be much harder to go around fixing all of the weird NSFW pictures placed in by new users than it would to simply check a linked image and approve the edit which is the status quo. Not to mention much safer for all those users who browse at work.
