evanphphelp

ok, i coded a gallery for myself and friends to post our artwork. i'm not new to php, so everything works fine, and i'm almost happy with it... the only problem is that i want to stop the possiblity of somebody saving our images. now, i know this is almost impossible, there's always a way, but to help with this i made a file called img.php img.php is what shows the pictures. i'm looking for a way to find out through php if img.php is being shown as an image in a page, or if it's being accessed by itself by the user by going to the page address. is there anyway to do this?
