Is this REALLY accepted as true? Photons are fast, but they're not instantaneous. They still take millions of years to travel between galaxies. For something to be truely timeless, I'd expect it to be able to teleport. Is this incorrect?

Assume a really fast rocket is traveling from galaxy A to galaxy B. Due to relativistic length contraction, the distance between the galaxies is less as seen by the rocket than it is for a stationary observer in either galaxy. So the travel time from the perspective of the rocket (the "proper time" of the rocket) is less than the travel time measured by a stationary observer. And when you work out the math, the rocket's proper time approaches zero in the limit as the speed of the rocket approaches light speed.

In the frame of reference of the photon, the moment it is created and the moment it is destroyed are one and the same.
