Is it possible to remove an uploaded picture permanently without deleting the entire answer? I uploaded a picture of a dead mouse on this question without considering it may be offensive to other users. I removed it at request, but it's still there in the revision history. Is the only way around this to delete the answer and re-post it?
Even if you delete the answer it will be still visible to mods and those with access to the tools menu.
I think the fact that you edited out of the answer should be OK in this case. Someone would have to go looking at the revision history to find it.
