Flickr has been around for a very very long time and is home to millions of images from amateur and professional photographers from all over the world.
If you’re using the Chrome browser you can easily add a bit of beauty to your desktop with the Flickr extension for Chrome that will load a random photo from Flickr whenever you open a new tab.
I’ve been using it for the last few days and it’s cheered me a little!
Get the extension here.
If anyone knows of similar plugins for Firefox or other browsers please let me know via the comments.
