But, in order to counter WotC's ruling on the images acquiring the magic of these types of spells, cast Faerie Fire on a Mirrored Imaged Displaced arcane caster and you will at least remove the Displaced aspect of his images and can pop them easier.
There's an interesting exercise in tracking changes here, too.
In the first printing of the 3E PHB, the definition of figments stated that figments cannot 'illuminate darkness'. And yet, there were a couple of spells, like Continual Flame, that were defined as Illusion (Figment).
In the second printing of the 3E PHB, these spells were changed to Evocation (Light), removing the contradiction. And yet, in the same printing, the prohibition on figments illuminating darkness was also removed... which means that the old school of Illusion (Figment) would have been acceptable!
Using the first printing of the 3E PHB, however, meant that Faerie Fire was an interesting counter to Mirror Image, assuming the ambient light level was dim. Someone affected by Faerie Fire is limned with coloured flame, and sheds light as a candle. The Mirror Image of someone affected by Faerie Fire is limned with coloured flame, but since figments cannot illuminate darkness, they
do not shed light as a candle.
So in dim conditions, when the wizard casts Mirror Image, you Faerie Fire him... and then attack the one apparent flaming wizard who is lighting up the space around him...
Unfortunately, now that the 'cannot illuminate darkness' prohibition has been removed from figments, the trick doesn't work.
