Data Encode Images
Speed up your site by using inline images via the data URI scheme to embed images directly within web pages. As defined by RFC 2397, data URIs are designed to embed small data items as "immediate" data in lieu of references to files stored on your server. This saves the number of HTTP requests you make by storing images inline. Opera 7.2+, Firefox, Safari, Netscape, and Mozilla support data URIs and Internet Explorer 8 does too.
