You can use getimagesize() and check if the image exists (there's file_exists() too, but it may not work very well, in this case).

You can use this function to fetch the greatest resolution screenshot of a particular video.

Code:

function fetch_highest_res ($videoid) {
    $resolutions = array('maxresdefault', 'hqdefault', 'mqdefault');     
    foreach($resolutions as $res) {
        $imgUrl = "http://i.ytimg.com/vi/$videoid/$res.jpg";
        if(@getimagesize(($imgUrl))) 
            return $imgUrl;
    }
}

Usage:

echo fetch_highest_res('Cj6ho1-G6tw').'
';
echo fetch_highest_res('VGazSZUYyf4');

Output:

http://i.ytimg.com/vi/Cj6ho1-G6tw/maxresdefault.jpg
http://i.ytimg.com/vi/VGazSZUYyf4/hqdefault.jpg

Note: This may not be the best solution, and it's a work-around if you don't want to use the API.
