medusa, photos are visible to everyone. This is something we struggle with, because we completely understand that some people might want them to be more private, but on the other hand our whole reason for starting YLF in the first place was to create a free resource for people who are looking for help on the Internet. If all the photos were private it would lose a lot of value.
Angie and I have talked about this many, many times, and if you have any good ideas for how we can achieve both we'd love to hear them.
One idea we have toyed with is to create a paid premium option that offered features like private photos. This would naturally ensure that only a fraction of the photos were private, but at the same time give people the option if they wanted it. This might also help us to get the site to a point where it was a sustainable business (another topic we talk about often these days ).
