Submission verification suggestion

I imagine Bill from IMDB verification looking at movies 24/7 to check every input users donate. Now I'm not after Bill's job, but it could help him save a lot of time if you let people add proof of their input. For example, I spotted an uncredited James Gandolfini in Under Siege (1992). Now is Bill really going to have to watch the movie, or could someone add a field for an approximated time stamp? Heck, why don't I just share a picture I took from my screen?

Bill just saved about 20 minutes of watching that movie!
