Baby Sharky

Dad is a steward with us on the Barclays tent at the Hay festival. He is so cute people stop in their tracks to photograph him - including a photographer who then wanted to use his image on a website as a stock photo. ( surely a signed release is required if you are charging £300 for use of a photo? - surprised when we found it on the site later)
Well I would at least ask or explain if I was the photographer!
