  Yes, the data uri is used by many userscripts (http://userscripts.org) for Firefox. It is interesting however that YSlow recommends that since it does not work on all the browsers.

  There’s a related entry in Rife’s blog [1] quite sometime ago.
  If not mistaken, its been the convention used by those porn site to spam people with porns and make sure they get it even if they are eventually offline. No I don’t subscribe to porns.

  Nice … just when I thought I’d read the URI specs inside and out something else comes along
  One drawback of this markup will be to reduce the cacheability of image data though, since in the default theme every page is marked as no-cache. We recently added control over these meta tags to the Builder theme and pages that used to take 3 or 4 seconds to load now take 1 or 2!

  You can also do this sort of stuff in CSS files, the benefit being that the CSS file can then be cached. We looked in to this stuff when developing Theme Builder 3.0 but decided the benefits weren’t worth it and that better caching of resources by the browser + merging of js and css files where possible yielded better results.
  Unfortunately there are issues with PNG images in IE 5.5 > 6.x and you generally need to have those as external files for various reasons.
  Another thing that’s well worth checking out is sprite images – ie. instead of having loads of little image files, create one bigger image with all the smaller images arranged in to a grid. You can then use CSS to display just the desired image from that file (in certain scenarios).
