[Message part 1 (text/plain, inline)]
Package: www.debian.org
Version: current

The PNG images from the http://www.nl.debian.org/Pics/ can be losslessly optimized (I saved about 23%).

Example:
http://www.debian.org/Pics/debian.png
original:  4412 bytes
optimized: 3586 bytes

http://www.debian.org/Pics/blue-lowerleft.png
original:  294 bytes
optimized: 155 bytes

All optimized PNGs are attached.



I am also able to decrease filesize of some GIFs by converting to PNG.

http://www.debian.org/Pics/banner-blue.gif
original GIF:  2938 bytes
optimized PNG: 1856 bytes

http://www.debian.org/Pics/logo-50.gif
original GIF:  1401 bytes
optimized PNG:  821 bytes

These two are also attached. I am not sure if the conversion of other GIFs (with multiple language versions)
is usefull, because some of language versions are smaller in GIF format and other in PNG format.

Nice day

Tonda Misek

Thanks!  I've uploaded the compressed versions to the repository.  The
new versions should be online in a few hours.
