As a designer you've probably needed to process a set of multiple images, all in the same manner. A batch processing of images might be a very useful approach in handling this kind of needs. Here at DryIcons we've found the use of some kind of a batch image processing tool necessary in order to provide various size icons in a very fast and very high-quality way, so we think it might be useful to share our batch experience through Adobe Photoshop's Batch.
The presentation will be done using Adobe Photoshop CS3, however things work pretty much the same in any other version (and perhaps in any similar software for that matter) and an average intuition and following the advises described here will probably keep you up on the right track.
