Yea, the planets are gigantic, and in distant orbits from their star. I don't think we even have the ability yet to directly image exoplanets much smaller than, say, Saturn, or closer to their stars than Saturn.

TL;DR - Two inside (16, 26AU) and two outside (43, 69AU) Pluto's orbit (39AU). They are all estimated to be a bit bigger than Jupiter.
