This doesn't address resource load requests made from JavaScript.  
(For example: setting img.src, setting iframe.src, making an  
XMLHttpRequest, using new Image(), using location.replace(), etc). In  
general it might not even be possible to transform the code to change  
URI references in JavaScript, since they may be concatenated from  
multiple strings or otherwise computed at runtime.

data: is also a pretty inefficient encoding for large chunks of  
binary data like images and videos.
