Note that this plugin does not attach Colorbox to any element because there are so many different options and usages. You need to do this in your theme yourself. Visit the colorbox site for information.

The plugin has built in support for 5 example Colorbox themes shown below:

<img src="%WEBPATH%/%ZENFOLDER%/%PLUGIN_FOLDER%/colorbox_js/themes/example1.jpg" /> <img src="%WEBPATH%/%ZENFOLDER%/%PLUGIN_FOLDER%/colorbox_js/themes/example2.jpg" /> <img src="%WEBPATH%/%ZENFOLDER%/%PLUGIN_FOLDER%/colorbox_js/themes/example3.jpg" /> <img src="%WEBPATH%/%ZENFOLDER%/%PLUGIN_FOLDER%/colorbox_js/themes/example4.jpg" /> <img src="%WEBPATH%/%ZENFOLDER%/%PLUGIN_FOLDER%/colorbox_js/themes/example5.jpg" />

If you select custom (within theme) on the plugin option for Colorbox you need to place a folder colorbox containing a colorbox.css file and a folder images within the current theme to override to use a custom Colorbox theme.
