How to change the margins around bullets in list in MS Word 2016?

I have a list in Word 2016, in which I want to add a pic from the internet for the bullet. I have the pic as the bullets but they are not centered to the text. They are above the text. If I use the usual black dot, that is in the center of the text to the right of the bullet. But when I put in a cartoon pic of a car to use as the bullet it is not centered to the text that is on the right of the bullet (car). I can't find any help for this. I only get results from my searches in google that tells you how to change, indents, or line spacing. But that doesn't help.
