 See tweaked images in the linked ZIP file. The tweaks are:

  1. A light grey border added to the preview image of the default colour
 scheme (light.png) so that it works better against the white background of
 the default Dashboard theme.
  2. Lossless compression of all PNG images of 2011.
  3. Removal of metadata from the JPEG headers and from their thumbnails,
 which saves quite a few kilobytes.

 I run the PNG images through optipng, advpng, and then optipng again, at
 extreme settings.

 The JPEG images I simply dropped on to Trimage (a tool similar to, and
 inspired by, ImageOptim for OSX).

 A further optimization for the JPEG headers would be to apply lossy
 compression, which will give us huge gains in size. I will open another
 ticket for that.
