Mirror Image

...Enemies attempting to attack you or cast spells at you must select from among indistinguishable targets. Generally, roll randomly to see whether the selected target is real or a figment. Any successful attack against an image destroys it. An image’s AC is 10 + your size modifier + your Dex modifier. Figments seem to react normally to area spells (such as looking like they’re burned or dead after being hit by a fireball)...

No, Mirror images do not get miss chance. Miss chance happens after a successful hit and a successful hit destroys an image.
