Back in the day, maps were oriented so East was at the top instead of North, hence the term "Orient". Now we arbitrarily put North at the top.
Photos of Earth from space are typically oriented to put north at the top to match the expected orientation on modern maps. Eventhough this relative orientation isnt necessary in infinite 3D space, it is useful for human perception. It's the same reason Ender Wiggam said "The enemy's gate is down". Relative orientations in space are arbitrary, but it makes it easier to conceptualize if everyone is consistent in how they use them.

Hey that's really interesting
That's why I crack up whenever some fool claims "Oriental" is "racist". It literally means "Easterner", much as "Occidental" means "Westerner".
It came out of Christians orientating maps eastwards towards Jerusalem. Sure, it's actually south east of Europe, but early geography was pretty challenging due to the difficulty of accurately surveying land over long distances so East was a close enough approximation.
