The Photoshop Action Pack provides 87 Actions (86 in the CS2 version, and 85 for CS) that allow you to control a tremendous number of Photoshop’s functions. In addition, the Action Pack includes special filter operations that let you sort images based on various criteria including EXIF and IPTC tags, color mode, size, orientation and aspect ratio. With the Photoshop Action Pack, you can execute complex batch operations that are impossible with Photoshop’s own internal Actions. In addition to filtering by file properties, you can create branching logic for more complex functionality. While Adobe Bridge provides a simple interface for launching batch processes, it limits you to only operating on the files within a single folder. Automator has no such limitations, and provides are more ways to launch a batch process.
Because Automator can control much more than just Photoshop, you can automate entire photography and graphics production pipelines. For example, you can use Automator and the Photoshop Action Pack to batch process the manipulation of your images and then automatically upload the results to a server, or archive them to a CD or DVD.
