and the canon service centre knows that too.
i can't imagine anything more embarrassing than sending your camera into service without removing the memory card. it doesn't help that there were more than 50 narcissistic photographs of myself with blood red lipstick and green eyeshadow. horrific i tell you, but the service centre guys would have had something to laugh about. (but then again, if they circulate it, i might become a movie star...)
my face may even be pasted on a dart board and every time someone aims well enough for a bullseye, i get a pimple. (although i'm quite sure there are a handful of people who may be doing that already...) grievances aside, i think it is only prudent that you be protective over your photos, even if you may want to be 'discovered'. your intellectual property is at risk too, and you never know if the person on the other side needs a subject for a voodoo experiment...
