Please give credit to Marko in your user profile if you use this mood theme: Ratatouille Mood Theme by <lj user="marko_the_rat">.
Upload the images to a web server. (The web server needs to support remote loading to LiveJournal—Photobucket works for this. Unfortunately, LJ's own Scrapbook is not suitable because it does not retain the filenames.)
Open moodthemecode.txt in a text editor and replace every instance of www.yourservername.com with your correct URL.
Go to the Admin
Console and enter:
moodtheme_create
"Ratatouille Mood Theme" "Ratatouille Mood
Theme"
Click “execute”.
Make a note of the mood theme ID number you get.
Replace every instance of YOURTHEMEID with the ID number.
Copy and paste the whole text of moodthemecode.txt (after making the changes described above) into the Admin Console and click “execute”.
If all is well, you should get a response page that lists each image and tells you that it was set correctly.
Go to Customize Journal Style and select “Ratatouille Mood Theme” from the pull-down menu under Mood Themes (it should be down the bottom under “Personal Themes”).
Click “Save Changes”.
