I notice google is now including large thubmanils of all sites when you search, and interestingly they appear as data:image/jpeg;base64,/9j/4A ...
What is the advantage of base 64 encoding the images like this rather than simply loading them through standard html img src tags?
I also recently noticed the base 64 encoding of a font like
src: local('Font Name'), local('FontFileName-Regular'), url(data:font/opentype;charset=utf-8;base64,T1RUTwAMAIAAAwBA
when this discussion was ongoing http://aota.net/forums/showthread.php?t=25749
and almost asked about the advantage of base 64 encoding the font right in the css file like that.
