I can't give anda an exact address for a higher quality version, but I can help anda find one you're happy with.
If anda cari via google Images, they have a new feature where anda can cari oleh using a picture anda have. As anda look at the cari bar, at the very right end is a pic of a camera - click it. Then anda can either input an link for the picture, atau choose to upload it from your computer files.
google will then cari out this specific pic and compile a grid listing of all the versions it could find. To get to the listing for the pic, you'll need to click on the thumbnail of the pic at the puncak, atas of the cari results page. You'll be redirected to the different versions of the foto anda searched for.
