Ambrosia has released Snapz Pro X 2.5.2 to fix an issue with accurately capturing the precise pixels of a selection and bring back support for several styles of image borders (which was excised in version 2.5). The update also improves the reliability of movie encoding, improves compatibility with both OS X 10.8 Mountain Lion and Retina displays, and adds Chinese and Russian localizations.

Find Photos in iPhoto in the Finder
Looking for the file associated with a photo in iPhoto? In iPhoto, to view a photo's file in the Finder, Control-click it and choose Show File from the contextual menu that appears. You can then drag the file's icon into an Open dialog to upload it to a photo-sharing service, for instance, but whatever you do, don't move or rename that file!
