This could work if security questions (not the best form of security by itself) are asked if the request comes from a "not previously used" computer. So that way, if the phishing site is sending a request on my behalf, they would have to answer my challenge questions (w/o human intervention i.e.) before getting to the image... that kinda makes life harder for an attacker.. of course the logic of identifying the "first time you are using this machine" thing needs to be non-stupid (for lack of a better word)
