That's not enough, unfortunately, because there is no way to specify a 
rotation for just a background and if you process the JPEG image to 
produce a rotated image (e.g. by painting to a canvas, getImageData, 
etc) you end up with some quality loss during the reencode.  And if you 
don't reencode you pay a pretty hefty memory price for keeping the 
decompressed data in memory...
