i am trying to find a way for a client to simply have a 2 way photo sharing site, and by that i mean we can post photos and have others also post photos all on the same site. i am basically looking for something like flickr but where both the client and others can post photos to the same place/page. i know that yahoo or google groups does this to a point but they are very cluttered and not really going to work for us. i feel like this is something obvious and available but i am failing to find it via google. any ideas?
A flickr group seems like it would be exactly what you need; this is what I use for several clubs I'm involved in. If you want it to look a little more professional than flickr, maybe try Smugmug? You can set up private communities which would seem to do what you want. http://www.smugmug.com/help/communities
It can, and the cool part is that others don't have to join any groups or communities. They just email their photos to the photo gallery.
