"Do you suppose the "night sky" would be about as bright as day due to the number of stars?" --> I seriously doubt it. Not an astronomer but: 1) Remember that you are looking at a 2D projection of a 3D galaxy. There's a lot more room between each star in 3D. 2) Hubble photos use massive amounts of time lapse to create detail[1]. The picture is being misinterpreted by your brain's intuitive sense of brightness in a typical night sky photo. The density of the galaxy seems fairly typical, it's just a really detailed photo. 3) Look up Olber's Paradox[2].
