I think you are misunderstanding how data URIs work. We make one JSON request to get N elephant images. We then place these into the DOM using data URIs specifically to avoid the request overhead you are talking about. If your network pane reports ~40 requests, then about half of these are not actually http requests. http://en.wikipedia.org/wiki/Data_URI_scheme#Advantages Stew
