Ah, but it's time that's in question- yes a picture is a fixed moment of time in the past but are we not viewing several fixed moments from the past when we (on earth) look at the stars? Are not the particles of light that we see in a fixed order from what you consider the past? Let's just assume for instance that a distance Star has already gone supernova or whatever else that may have happened to it the light that we see on earth is just a remnant from the past so much as a photo maybe a remnant from the past such as a deceased grandfather. The star either is our is not currently at this very moment. What we are seeing is a remnant of a moment not what is. An old movie that we're being shown for the first time.
