On further reflection.. Anyone out there with a passport issued in the magic window between October 26 2005 and October 26 2006 (like mine) where the US requirement is for a digital photograph (but not bio). I *think* my passport has a digital photograph but am unsure how to confirm. I called UK Passport Service but they were unable to help; I have an email query pending which also wasn't answered properly first time around.

(Or does anyone know how to tell if it's a digital photo?)
