From the frame of reference of the photon, time moves infinitely quickly, so it arrives at its destination immediately after departing its origin. If it were to travel forever without ever being absorbed, it would still experience that infinite journey in a single moment of time.

This is one of the things that periodically blows my mind: look up, and that photon from that galaxy has traveled for millions of years and for a jiffy, and just here its wavefunction has collapsed on one cell in my retina.

Its not really accurate to say that infinite time has passed infinitely quickly. The best way to put is that distance for a photon doesn't exist.

This 👆 The photon has left and arrives at the same time from its frame of reference and time is irrelevant. So your question has no meaningful answer.
