Twice today a user has taken it upon him/herself to edit my post to remove what I think is a useful piece of visual information (the cover of a book which also has a graph that I make repeated reference to in the post). This user's edits don't have to pass the review queue because s/he has sufficient rep. Yet the user continues to override my reversion of the edits.
What should I do? I don't think a war of edits is particularly helpful. The user has not attempted to contact me to discuss the issue, so I can't tag him/her in a comment.
