If he does he shouldn't be posting them here. He should be giving them to his insurance company so they can go after the other driver's insurance company for compensation.
I'm confused. Digital images can be posted here AND sent to an insurance company. What am I missing?
You could potentially post evidence against yourself if you posted online. It's a little shady but I don't think many people are ok with shooting themselves in the foot.
If the images contain information that is relevant to an insurance claim, they probably should not be posted in a public forum that everyone on the Internet can see.
