What the Heck Is Bridge?
Bridge made its first appearance in Photoshop CS2. A basic image manager that was overlooked by many users, it did offer some interesting features including the ability to work with RAW images without launching Photoshop and to easily rename images. Keywording, searching, and organizing were also core features that made Bridge more useful than many people realized.
For CS3, Bridge adds some useful new features that should make this a more popular option for managing your media files. (And not just images, either. Bridge can work with audio and video files as well.)
