Well, your grammar was good. No worries there.

As for the image thing, I think that philosophy is more suited to downloading files of a large size. Some downloader programs operate by cutting the file into pieces and downloading several of them at a time for supposedly faster download speeds.
But on GIFs, I don't think that works quite like it's supposed to. If you have one image, the browser sends one request to the server and the server sends the image back. But like you've got it, the browser has to send three dozen requests to the server, the server has to send three dozen images back, and the process is rather counterintuitive. GIFs are small enough anyway that I don't think it will make that much of a difference in speed.
Someone else may have another view on that, but that's my general take on it.
