How can I change the Liferay bookmark/favorites icon?

There Are Many Methods to Change Bookmark Icon.......... Some of those are mentioned below
hope it will help You..........


Method 1
By dropping your own icon with the same name as the Liferay icon, your icon will appear as the bookmark/favorites icon instead of the Liferay icon.
The icon is located under:

       /Your_Theme/html/themes/example/images/liferay.ico

An example
        
/portal-web/docroot/html/themes/brochure/images


------If you create your own theme with the Plugin SDK, place the icon in themes/Your_theme/docroot/_diffs/images/liferay.ico


Method 2
Modify your portal-ext.properties file (if it supports that):

#
# Set the theme's shorcut icon.
#
theme.shortcut.icon=liferay.ico
