Dispell magic

[OrlockDelesian]

Let's Assume that there is a wizard under the effects of mage armor, mirror image, blink and blur. An enemy caster casts dispell magic on him. If the spell targets the actuall caster, all 4 spells end. But what if it hits the image?

Do the mirror image spell ends?
Or does nothing happen?

Dispel Magic is not an attack (because it doesn't involve an attack roll). Therefore it cannot hit an image and always hits the creature.
