These points may have been brought up by Pyatiugolnik, but since they have blocked me I don't know.
But anyways...my characters are my characters. Other people should not be able to edit stuff like this without permission. Some images are very important to people even if the characters are owned by multiple people, the other person/people should not be able to delete the images. It's like if you were able to remove a single paragraph of information from the HTML, it's a part of the character and should not be editable by people that you have not allowed to do so.
In fact, I think this could go well in conjuction with the character co-ownership suggestion brought up a while back. (Can't find it right now...) I imagine that then characters that are co-owned could have the images be edited by both parties, because they also own the character. But if me and some rando have made an image and the rando then deletes the image from his gallery because he's gonna sell the character or whatever, I don't want it to be removed on my end, because it still includes my character in it. Having character co-ownership and/or giving people that are not in loco artist-is (i.e. the person who uploaded if credit is given to off site, or the person credited onsite) rights to edit the image would make sense.
Yeah, I think that's what I would like: an "in loco artist-is" role that the person in the role for the image can turn on or off other people editing the image, similarly to how people can edit what Authorized vs. Public users see when viewing the image.
