We're an online publisher with a large collection of photos (our own and those we buy from stock providers). iPhoto, Aperture, Lightroom -- terrific if you're a photographer who works alone. We need a collaborative tool. Any suggestions? So far the possibilities I've thought of are not appealing: 1. Set up a Mac mini with iPhoto and get everyone a LogMeIn account to access it. Put someone in charge of adding all new photos to the iPhoto library. 2. Use Flickr, make all the photos private, and share the login company-wide. Thank you.
