About two years ago, I selected EasyBatchPhoto from a group of contenders. My top priority was image quality. EasyBatchPhoto's adjustable Scaling Quality and Sharpening brought it out on top. The ability to create (and modify) named presets of scaling options is a big time-saver.

I've recommended EasyPatchPhoto to two of my clients (both art galleries) for batch processing photos. They're as happy as I am.
