Which of these men is the one true Pope?

[Triforcer]

I think based on photographic evidence of holiness alone I'd entrust my immortal soul to the Holy Father Gregory XVII.  But Michael I's second picture makes it close.  Can anyone find any other popes?  These are all I could find who had websites, a few others just had wiki entries.
