Advantages and disadvantages of using base64 encoded images

Question

I am thinking of using base64 encoded images for a site I am working on to optimize the load time.

Anyways, before I start, I was wondering: what are the advantages

Answer 1

also the response time of the HTML page will increase, because images loads asyn in normal scenario. even if images loads late you can start seeing text.

Another advantage of CDN would lost if only media is being cached in CDN

that advantage will be lost.
