Edit: You're welcome to use my mood theme images! But if you do so, please copy them to a server of your own so you're not using my bandwidth. I'm providing a ZIP file and a tarball with the images so you can upload them all at once rather than having to copy one at a time from the moodtheme listing. Pick one archive or the other; both contain the same files. The tarball is smaller (6K vs 16K), but the ZIP file is probably easier to work with if you're on a Windows system.
The file also contains a file called "console.txt" that contains the commands necessary to set up the mood theme; just replace "http://moodthemes.mizinamo.org/kanjithe
Oh, and if you use my mood theme, I'd appreciate it if you drop me a line (email address is in my userinfo) to say so, just so I have an idea of how many people use it.
