ColorBox integration in Magento

I want to add ColorBox jQuery in my Magento website. Is there an specific method for this?

Or do I have to 开发者_Go百科make the changes in .phtml files?

To add new javascript library on all your pages use layouts. Create new layout file yourmodule.xml and put there code

<default>
    <reference name="head">
        <action method="addItem"><type>skin_js</type><name>js/colorbox.js</name><params/></action>
        <action method="addItem"><type>skin_css</type><name>js/colorbox.css</name></action>
    </reference>
</default>
