Yes, there are indeed easy fixes. The problem is, I shouldn't have to be fixing anything. The images were fine as I had them. His edit broke over a dozen links. All of which I had to manually edit to fix.
I could have just reversed what he did, but as his intent was good I didn't see a reason. All I am asking is that in the future he does not touch a faction's wiki page nor their media without permission.
I don't think that is asking very much, seeing as it is only common courtesy.
