Great improvement! Now it mostly retrieves music-related pictures. Trying now with Eagles, Scorpions, Genesis, Cream, Journey, Cars and Yes, it no longer shows a football team, animals, automobiles, food, or travel images and most of the retrieved images are of the specific band. It still shows no band picture for Love, but I guess you have to use local pictures for some artists unless they are widely popular with a unique name.
By the way, after re-enabling google, it didn't work immediately and I had to restart MB to make it actually show images from Google. Is it expected?
