One of the things to consider when moving your images to CSS data URI's is that unlike images, CSS blocks the rendering of the page. While it's smart to move small images (think 4kb or less) to data URI's, bigger images should be kept separate. That way you aren't blocking the display of text or other elements on the page, while those larger images are being downloaded.
