How can I programmatically check if a Google User's profile picture isn't default? <p>A Google User's profile picture defaults to <a href="https://i.stack.imgur.com/34AD2.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/34AD2.jpg" alt="https://yt3.ggpht.com/-_fExgATRXLY/AAAAAAAAAAI/AAAAAAAAAAA/-fmo8LhN7Pg/s240-c-k-no-rj-c0xffffff/photo.jpg"></a><code>https://yt3.ggpht.com/-_fExgATRXLY/AAAAAAAAAAI/AAAAAAAAAAA/-fmo8LhN7Pg/s240-c-k-no-rj-c0xffffff/photo.jpg</code></p> <p>I want to check to see if a user has updaed their picture to something besides their default based on the URL for the image. Is that possible? Is there another way to check?</p> <p>EDIT: A URL of a google profile picture that has been set is this: <a href="https://i.stack.imgur.com/SmPuE.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SmPuE.jpg" alt="https://yt3.ggpht.com/-zSpYe-dpPNk/AAAAAAAAAAI/AAAAAAAAAAA/EVfQSDPEeQc/s240-c-k-no-rj-c0xffffff/photo.jpg"></a> <code>https://yt3.ggpht.com/-zSpYe-dpPNk/AAAAAAAAAAI/AAAAAAAAAAA/EVfQSDPEeQc/s240-c-k-no-rj-c0xffffff/photo.jpg</code></p>
