What makes this app so helpful is its ability to apply filters to your results so, for example, you can look only at photos licensed under Creative Commons (more likely to be legal for noncommercial use), or you can sort by minimum size (up to 1,500 pixels) or by Flickr's 'most interesting' property. The app's well-designed, streamlined interface is centered, fittingly, around Flickr search results: you just type your terms into a search bar (specify text or tags in a drop-down menu), and the main window is quickly populated by results that you can preview, download, or open in Flickr using your browser.
Viewfinder is a desktop app that makes finding and downloading photos from Flickr much faster and easier.
