“Featured Gallery” Above The Posts?!

Howdy. I would like to know how I can add the plugin “Featured Content Gallery”, so that it would be above the posts in my web site. They gave me a PHP code that I need to paste where I want the gallery to show, but I don’t know where I should paste it.

So my question is: Where in my theme files should I post the gallery so that it will be over the posts in my homepage? (For now it will be over the pist “I love you, Man.)”

Thank You!
