I find it interesting that the pictures on the site are a) served as lossless PNGs, and b) dithered.
Removing the dither, and switching to heavily compressed JPEGs, would reduce the file size of the images by ~60% (I've just done it in Paint.NET), thus reducing network usage per request, which in turn would shave a bit off the power consumption.
