I reduced the image to 200x200 pixels (Browsers will scale it to 400x400) and
32 colors which gives an file size of about 15K. 400x400 pixels will always be
above 50K with PNG. JPG helps here (35K), but then the html files have to be
changed.
The original file is saved in title-big.png.
Reassigning to Jan, because the latex2html configuration for generating this
image has to be changed.

Is the size of an index png also so big?
We should reduce the size of the image
and stop the scaling.
The scaled image looks ugly. |

May I recommend 'pngcrush' for getting those PNGs as small as they can be.
http://pmt.sourceforge.net/pngcrush/
on debian:
apt-get install pngcrush
use:
pngcrush -brute infile.png outfile.png
note reducing the size of the color table is the most dramatic way to shrink
the file size..
have fun,
Hamish

pngcrush does not reduce the 15k image anymore (except for 12 Bytes). :) |

Jan: Did you actually change the latex creation for this image, so we can
solve this issue? |
