You are

A Cappuccino

They put pictures on me then take pictures of me to share with the world

Barristas create quite fancy artwork on the milk foam on top of your cup. Many people take pictures of that and post it on Instagram, facebook etc.

But the pictures disappear as my end draws near and anxious heartbeats stilled

When the cup is empty the milk is gone. "Anxious hearbeats stilled" refers to the addiction some people have towards coffee

I am sought after very wide especially after every night when things are put in motion

Many people drink coffee, especially in the morning (In Italy you drink Cappuccino only in the morning, in the afternoon you would go for an Espresso). Coffee puts you in motion.

And after a little while I will be able to defile your ability to sleep with devotion

Well, Coffee can keep you from sleeping, after all that's why most people need it in the morning
