Feeling Lucky is a small application created by Bonstio for Google App Engine which retrieves and displays random images. What could simpler? We use the Flickr API to retrieve a random image from a specified public Flickr group. You can add a random image to your own website or application like our own iGoogle gadget or this example mosaic - just hit the "get the code" link.

Even amazing wallpaper sites struggle to deliver images big enough for multi-monitor systems (greater than 5000px wide) so be sure to check out the huge option which is great for finding ultra-high resolution images. We automatically resize the images when they have loaded (and when you resize your browser) so you can fully view them. Simply right click and 'save as' to download the image ready to use as wallpaper.

For huge images, wait until it's loaded & hover over to show the zoomed detail.
