Not necessarily. The way I've always had to rationalize the
thermographic thing is that your body does not actively emit light, and
thus it is easy to fool someone into thinking you're not there. Your body
*does* actively emit heat, though, and disposing of this energy is not
feasible.
But this just goes back to the age old discussion that physical
illusions should be manipulation spells, and mana illusions shouldn't care
what form of perception the person is using. But I digress...
