I found this really nifty widget that lets you search through the millions of photos on Flickr.com. Its really fast to!
When you find an image you like you can click on it to see a larger version and it also tells you all of the images available sizes. You can click one of the available sizes and it’ll bring you to Flickr page displaying the image in that size.
You can download the Flickerator widget for free from DavideZanotti.com!
