Every now and then I find myself working on slides in Keynote and writing Download Squad posts - and struggling to find a suitable image. Of course, Flickr is the best way to find images - their clear licencing and Creative Commons support makes finding images fairly straight forward. However, getting the image into Keynote isn't entirely painless. The workflow of browsing search results, viewing the image and then finding it at a suitable size (if it exists) takes time - however that's where Viewfinder steps in.

A native Mac OS X application (requiring Mac OS X Snow Leopard), Viewfinder allows you to search Flickr from the desktop apply filters to show only Creative Commons images, and specify a particular image size. Then, once you select an image you can download the image, set it as your desktop background - and most importantly - send images straight to Keynote for your slides.

If you're a heavy keynote user (or blogger) who frequently needs to find Flickr images for your work Viewfinder is indispensible. I've been testing it since early September and found it an incredibly convenient tool to have at hand. A licence costs £15 (roughly $25) and a free demo is available for you try from the Viewfinder webpage.
