From Karelia Software:
Built from the ground up to resemble the media browser found in several Apple applications, the Karelia iMedia Browser is a stand-alone utility that can be used to quickly access a user's library of photos, sounds, movies, or bookmarks. The Karelia iMedia Browser allows users to browse their libraries of photos (iPhoto, Aperture, and Pictures folders); music (iTunes library, GarageBand songs, and Music folders); movies (from iTunes, iPhoto, and Movies folders), and bookmarks (from several leading web browsers). It can be activated either from the dock or from a small icon in the menu bar.

Improvements to accessibility; show default selection on first run of the application; iPhoto and LightRoom parser improvements; improvements to Flickr query editor; French localization updates; bugfixes
