@matpacker Doesn't Flickr already provide viewing privacy tools?
@khurtwilliams correct, and that’s where I would host my photos more often than not, however, in this instance it’s photos of kids and a couple of the parents aren’t keen on having photos on anything other than my website... I’ve tried to explain to them that there’s no difference, but I gave up in the end.
@matpacker understood. That makes thing challenging. You would now be fully responsible for any security/privacy issues. I'd ask them to sign a contract.
