[Plugin: TheThe Image Slider] Where does the php code go in the Twenty Eleven header?

Hi, I downloaded the plugin TheThe Image Slider. I’m using Twenty Eleven child theme. Does this plugin work for my theme type and for my header images? If so, where does the code go exactly in the header? Do I need to remove any other codes within the header to make the slider work for my header images? I currently have 4 header images uploaded that alternate on refresh. FYI: I have the plugin Twenty Eleven Theme Extensions installed and I have altered the height of my headers within my theme to 530px with that plugin. The width is still 1000px for all header images.

This is what my header.php looks like:

Where does the slider go? Where does the slider code go? What other code should be removed, if any? Because it’s not working. I’ve tried placing it in different areas of my header. No luck.

<?php
if (function_exists('get_thethe_image_slider')) {
 print get_thethe_image_slider('Slider1');
}
?>

I hope someone can help and replies. I’d appreciate it. I really want my header images to slide or do something lol. I want to make the site look cooler. ??

Thanks,
Christina
