  You should have paid more attention on the jpeg compression parameters
you used for these images.
  These images present pathological cases for jpeg compression, which
causes very visible artifacts. It's difficult to see what are jpeg
artifacts and what are radiosity artifacts.

  Besides using less compression, you should also use 1x1,1x1,1x1 color
sampling (if your image conversion/manipulation program allows configuring
that; if not, use gimp or cjpeg).

  Of course another option is to use png instead of jpeg (remember to
run the png files through advpng and pngcrush to minimize their size).
