i have a client who wants me to design a system v v similar to a photography site like istockphoto. so users buy credits and can download photos. problem is, obviously the photos have to be stored in a directory somewhere, like www.mysite.com/photos/photo1.jpg.
so how can i stop people just visiting that link, right clicking the photos and saving it? thus sharing it around with everyone and not having to pay. can i do this with php. or perhaps .htaccess??
cheers
