Hi @gavvet saw this come up my feed and noticed nobody else answered it. So I'd thought I'd chip in!

You can tell that the sun is to the upper right because of the illumination on the moons. Because the earth is the same orbital plane as Saturn, the Earth must also be in that direction. Therefore we will see a view where we are looking down at the rings at an angle, wiith the rings passing across the bottom of the planet.

Just to confirm this I looked up the link for PIA18352 and it was taken on Sep 24, 2015. Using Guide 9.1 this is how Saturn was predicted to look from earth on that day.
