I always wondered how to replace the konqui-icon in the shutdown-screen. Now that I know how (thanks to connectiva8's posting yesterday) I wanted to customize this according to my favorite wallpaper :)
The file has to be placed in either /opt/kde3/share/apps/ksmserver/pics (systemwide) or $HOME/.kde3/share/apps/ksmserver/pics (changes the icon for one user).
Please rename the original picture of konqi before you copy mine into this directory or else it will be lost.
I run 1280x1024 and the size in the download works fine for me. For smaller resolutions just click on the two previews and save the pic. (The black background is really transparent. You'll see when you click on one of the previews.)
