Did George W. Bush paint his portraits from Google Images?

Art critics have been less than impressed by George W. Bush’s exhibition of his paintings of world leaders, but even more interesting is that the sharp-eyed Greg Allen noticed that the paintings have taken more than a little inspiration from the top images of the leaders on a Google Images search.

Does this make the former President a “lazy artist”, or was he using the Google Images search results, many of which are form Wikipedia, as merely inspiration and tried to paint the individual’s personality with his brush?
