Images don't work. Didn't work for Emmett Till and won't work now. We desensitize very quickly. And worse (I really hate to say this but), the images end up on some sicko child porn site or in a video game. Yes, there's a first-person, virtual reality video game in which you are the Sandy Hook shooter. I've seen that one; I'm sure there are many more. What works is what Australia did; ban assault weapons. 60 Minutes did a great piece showing the difference between an AR-15 wound and a .22; .22 clean wound, straight through. AR-15? Literally blows your guts/brains to smithereens. No useful purpose whatsoever. Can't hunt, meat is no good. Maximum gore killing, that's all it is.
