One of my web site customers has hundreds of images that need to be sized and optimized for his site from time to time. Here's how I use Photoshop for to accomplish this efficiently: Isolate and save all the images into a ''Source'' folder - use ''Window > Actions'' to record and save all the ''Actions'' needed to modify one image - use ''File > Automate > Batch'' to apply the recorded ''Action'' to all the images in the ''Source'' folder and put the final images into the ''Destination'' folder. After that I FTP the files from the Destination folder to the web site.
