Last week, we launched the ability to set an image of users' choosing as the background for the Google homepage. Today, we ran a special "doodle" that showcased this functionality by featuring a series of images as the background for our homepage. We had planned to run an explanation of the showcase alongside it-in the form of a link on our homepage. Due to a bug, the explanatory link did not appear for most users. As a result, many people thought we had permanently changed our homepage, so we decided to stop today's series early. We appreciate your feedback and patience as we experiment and iterate.
