You might first try doing lossless compression using optipng, pngcrush or
advpng. If lossless compression (and dropping of metadata) doesn't save
enough than look at using the convert command (part of ImageMagic) to
reduce the number of colors. I would expect that blurring and noise reduction
would allow better compression and would also reduce the image size.
Shrinking and rexpanding should also allow for better compression.
