[Plugin: TheThe Image Slider] Where EXACTLY put code to replace header pic?

Hi all,

page: playcentreforums.co.nz (not much to see yet).

This is a steep learning curve for me, but I’m working on it. Please bear with me for a moment:

I have my Twenty Eleven child theme, including a child header.php, which so far is an unaltered copy of the default twenty ten header.php.

I understand that I have to copy the following into my child theme’s header.php, with “Landingpage” being the slider that I want to replace the static header picture with:

if (function_exists('get_thethe_image_slider')) { print get_thethe_image_slider('Landingpage'); }

I have some experience with HTML, CSS, and WordPress, but no experience with php, but I’m thinking that the two questions I have are probably not too hard:

Q1: Where in the code of the child theme’s header.php exactly do I have to put the above code in order to replace the header picture of Twenty Eleven with the slider?

Q2: Which parts of the existing code in the so far unaltered header.php do I need to change, delete, or replace with above code?

I hope that I am right assuming that this can be answered in one or two lines. If not, I’d be very happy, too, if you write a few more lines – any help much appreciated!

THANKS!

Matt
