I know copyright has been discussed ad-infinitum here but this dovetails into the post by Chuck the other day on pulling photos from the interned and posting them here.
There are companies that troll the internet on behalf of photo distributors searching for copyright protected photographs. Once they locate one, they contact the owner and strong arm the offender with threats and a high fee to resolve the grievance. One of my employees saw a cute photo of a dog with a bandaged leg and put it on our website a while ago. I received a strongly worded e-mail to take it down immediatly and pay them $800 or the fee would continue to rise. I did some research to discover the photo distributor and am in the process of negotiating a settlement, thereby bypassing the heavy-handed third party.
Our web posting protocol has now been heavily modified and, if Chuck seems paranoid about random photos and material, it's because there are people out there looking for such offences and wanting to profit from them. An expensive lesson for me
