Connected Flow, maker of DarkSlide for the iPhone, FlickrExport for Aperture and FlickrExport for iPhone, has announced the release of Viewfinder, a Mac app which helps you find, download and use images stored on Flickr. It’s priced at £15 (about $25).

Flickr is the enormously popular photo blogging and social networking service owned by Yahoo. It currently contains more than four billion photographs, many of them available for reuse under the Creative Commons license. Viewfinder helps you search that massive database for images you might want to use.

Viewfinder helps you search tags, titles and descriptions of publicly available Flickr images; it generates attribution text for you and checks to find images with Creative Commons licenses.

System requirements call for Mac OS X 10.6 or later and Keynote ’08 or later for integration features.

Connected Flow plans to raise the price of Viewfinder to £18 (about $30) once Viewfinder 1.1 is released.
