Inlining images into HTML with Base64

Base64 encoded images become part of the html and displays without loading anything instead of a web browser having to download the image.
The main benefit is that a webpage does not have to load an external image. Reducing the things a webpage has to load will naturally make that page faster.
It is best to only base64 encode tiny images. If you try to base64 larger images you will end up with a great deal of code in your html and lose out on the performance benefits.
