Where do publics like: @lazy_english (on Instagram) get pictures for the background?

Question

Images

There is a public on Instagram, for example: @lazy_english. This public exposes English words and translation to them.

I have a question, where do they get such pictures, and most importantly very matched to the word?

Answer 1

They pay money to a specially (un-)trained person to manually select.

Answer 2

Or maybe ask the owner of this public?
If you remove emotions, ethics, etc. and leave only rationalism, this is the easiest way.
