Look. You need to understand how css works. Seems that you are not familiar with that. You are trying to add image with 500px*500px https://joxi.ru/vAWK9pySgx8j0A to icon 16px*14px https://joxi.ru/DrloX9piVz7b1A

You have two options:
1. Change image size to 16px*14px
2. Or add this css here https://joxi.ru/LmGeB0jIwNWRbA

background-size: 18px auto;
background-position: center center;
