This is just a heads-up for those posting their galleries on social networking websites.
If your main intent
is to share your (selected) galleries to pretty much everybody
using Facebook, Google+, MySpace, or whatever (as your chosen photo gallery hosting site). Please set only those selected galleries
as "Public" so people who don't have an account on Facebook, Google+, MySpace, etc. can at least still view & enjoy the photos (through the direct URL gallery link). Also, some companies/schools may prevent people from browsing Photo Galleries if they detect someone logged in to a social network website, but they still allow people to view photo galleries if no one is logged into his/her social network site account, and "Public"-setting--enabled Galleries can be viewed without being logged in.
If you have photos you only want your friends to see, it is probably a better idea to put those particular pics in a separate Photo Gallery and set that as "Friends Only" or some similar setting.
