Skyrim - Alduin's wall quest question

I’m stuck in front of 3 rotating pillars with pictures on them. Esbern said something but I couldn’t hear him… Does anyone know how to solve this puzzle?

there should be pictures to the left of you, on the bridges

I really don’t see squat. There is a bunch of big pillars throughout the room, if they have something to do with it.

Alright this can be closed. Just did every combination possible with the pillars and got it.
