I have an iMac and an iBook, both connected through Ethernet.
File sharing and iTunes sharing works perfectly. However, iPhoto sharing only works in "one-way": from the iBook, I can access the iMac's shared photos. When I try to reach the photos on the iBook, the shared library icon does appear in the "source" pane, I click on it and it starts loading the pics. Suddendly it will stop loading without any warning, taking me back to the library on the iMac (though the shared icon stays visible...)
Any solutions? It's really a bummer, as I planned to have all my photos stored in the iBook and still be able to "see" them on my iMac
