Flickr is a wonderful resource, with millions of images online. Like many vast resources, finding that perfect image can be a real challenge. I search for images of products on Flickr in the course of my work, and a utility I use to expedite those searches is Viewfinder for the Mac.
Viewfinder has a simple interface that allows me to find images that meet my needs. A few taps on the screen and a good search topic and in seconds I have lots of images from which to choose. I can then go straight to the image page on Flickr or download the image with a click of the mouse.
There is a free version of Viewfinder that is somewhat restricted. The full version is only £15 ($22) and is well worth the price. Take a look at the program in action and see if Viewfinder might work for you.
