I was just reading a book to put my 4 year old to sleep, and there is a part where there is a satellite that took a picture of pluto, considering how far pluto is, how can the satellite send the images back to earth with that distance?

Slowly.
Strictly speaking, that photo probably did not come from a satellite, but rather a probe on an escape trajectory.
As for how, they get a huge antenna on the probe, point it at a huge antenna (or several) on Earth, pump as much energy as the probe can spare into the signal, and transmit data slowly.
