advantages and disadvantages base64 image encode
===

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

Anyway before I start I was wandering what are the advantages and disadvantages of doing this.

At the moment I don't see any disadvantage but also I noticed is not a technique used very often and that makes me wander if I didn't miss something.

After googleing the subject I didn't find anything clear so I decided to ask here.

So... any opinions?

Thank you and have a great day.
