While iPhoto permits snapshot sharing over a network with Rendezvous, It’s The Content’s (ITC) free service ShareALot allows you to share your images with anyone on the Internet. It acts as a conduit for both hosting your photos and viewing those shared by others who want you to see them; both are displayed on a local Web page residing on your Mac’s hard drive.
After you install the application, you simply drag and drop as many photos as you want onto its icon and decide who you want to share them with. Any recipients who don’t have ShareALot installed on their computers yet will need to do so before they can view your photos.
ShareALot requires Mac OS X v10.2.x “Jaguar” or higher. You can share photos with Windows users and vice-versa.
