:Sure. The IP editor is a person known as Russavia who is one of only half a dozen people who have been banned from interacting with any Wikimedia Foundation projects - basically, Russavia is unable to 'play nice' with other users to the point where he sends them abusive messages off-wiki if he doesn't agree with them. I removed the image because Russavia added it after his ban had been put in place - then Russavia, via an IP address, re-added it, with the edit summary "hey richard symonds you enormous a*****e, funny you accuse me of harassing you and yet here you are acting like a c**t destroying content  get a life ya pathetic f**k" [my redactions!]. As far as I can see, a registered user hasn't re-added the image at any point, only Russavia has - you might want to check again though, I could be wrong!  
 :In short, though, I have no problem with the image being in there. It's a good image, and you should feel free to re-add it if you want to. I just have a problem with Russavia adding it because he was banned from our project for good reason, and I don't think it would be fair for him to be allowed to edit, but not other banned users.
