I was looking for a handy application for editing my photos and stumbled upon ImageWell. ImageWell is not as fancy as Photoshop but it is very useful for everyday tasks, such as resizing, cropping, and rotating images. You can save the images in PNG, JPEG, or TIFF format and even add watermarks (for very secret or copyrighted stuff :) Oh, I forgot to mention that ImageWell is freeware and available for Mac OS X only.
