See the about page: after the theme is installed and selected, type chrome://global/skin/about/about.html in the urlbar for information on subskins, licenses (GPL & LGPL), email contact information, etc.
To apply subskins, put the appropriate import url at the top of your userChrome.css and/or userContent.css. You can right-click and save these two files to your profile's chrome folder; they will apply the subskins for menuicons, button icons and about:config:
userChrome.css userContent.css

GNU/Linux version: only for GNU/Linux; optimised for best appearance. May include more subskins.
The VectorLinux Edition is essentially the GNU/Linux version, but also features VL throbbers by default, and has Vector-specific information in the about page. The default throbber is available as a subskin. Although packaged for Vector, it should be suitable for any GNU/Linux distro.
To upgrade a previous installation of a theme, close SeaMonkey, then navigate to your profile, and replace the old theme-name.jar with the updated theme-name.jar.
Or, you can go to Edit > Preferences > Appearance > Themes, and uninstall the theme from there. Close SeaMonkey, navigate to your profile chrome directory, and remove the old theme-name.jar. Then, restart SeaMonkey, and install the new version.
If you wish to uninstall the theme, do so by going to Edit > Preferences > Appearance > Themes, select the theme, and uninstall.
If you are updating from Orb Colours Classic to Eurynome, you must install Eurynome! You cannot simply replace orbcoloursclassic_sea.jar with eurynome.jar.
Problems installing? Check that javascript is enabled and software installation allowed: Edit > Preferences > Advanced > Software Installation. Also, check that incognu.com is allowed to install software.
(VectorLinux users: some of these instructions do not apply to VL SeaMonkey packages, in which the themes are pre-installed in the SeaMonkey app's chrome directory: /opt/seamonkey/lib/seamonkey-<version>/chrome)
To uninstall an iconpack, visit the IconPack Uninstaller/Restorer at iconpacks.mozdev and look for "Restore my SeaMonkey/Mozilla Suite icons".
Note that installing an icon pack requires root privileges, since the iconpack must overwrite SeaMonkey app directory/chrome/icons/default. You may prefer to download the iconpack, extract it with unzip iconpack-name.xpi, and manually replace the icons.
