PhotoWorks launched PhotoStreamer 2 today. This free application allows Mac users to upload large amounts of digital images as well as view, organize, and order prints directly from the desktop. The software works with iPhoto, Photoshop, and some other Mac photo applications. PhotoStreamer 2 features captions, rotation, and a zoom tool that lets users control the number of images in view. PhotoStreamer2 requires Mac OS X 10.4 or later and is available for free here.
