We can compress png images (especially the once created by using colored scanner) using 'pngcrush', 'optipng' or 'advancecomp' tools.

mkdir output pngcrush -d output -brute -l 9 -v file1.png file2.png ... filen.png
optipng
optipng can be used as follows:
mkdir output cp file1.png file2.png ... filen.png output cd output optipng -o7 *
