How to make my IPhone 4S work again?

My IPhone 4S is shutting down on me. It has been messing up but today it just shut down because the battery died and then it wouldnt take a charge so it was just dead. I need some very important pictures off there. But it now is just flashing the apple on and off. So how could i it to work? Or is there someway i could get the pictures off?

It should work after a few days, and then see if it works.
