Jamawkinaw Enterprises has released Downcast 1.0.11, which adds an option to switch to audio-only playback of video podcasts. Selecting this option in the video context menu closes the video but continues playing the audio. The podcatcher app also squashes a bug that caused file extensions to be dropped for imported episodes, fixes priority play for playlists, ensures that statistics for partially played episodes are properly refreshed, fixes a problem that prevented the selected podcast/playlist from being reselected after a restart, and fixes multiple bugs that could cause crashes. ($9.99 new from the Mac App Store, free update, 6.4 MB, release notes)
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!
