Using IF statement on is_page to change images

Two ways you can do it. Pick one

1) Put an IF statement inside of header-col3.php to display different images based on the page that is displaying,

inside /header-col3.php will be an IMG tag with the header image
<img src=" a file path is here " alt=" something " />

change to

<?php if ( is_page('Home') { ?>
   <img src="   home header file path goes here  "  alt=" something " />
<?php } elseif (is_page('Booking Procedure')){ ?>
   <img src="   default file path goes here  "  alt=" something " />
<?php } elseif (is_page('Contact Us')){ ?>
   <img src="   contact header file path goes here  "  alt=" something " />
<?php } ?>

2) OR, another approach, make different template files for Home and Contact.
for example, /header-col3-home.php and /header-col3-contact.php

To do this copy /header-col3.php to the other two filenames.

Then change /header-col3-home.php and /header-col3-contact.php to display the image you want. Your PHP would look like this:

<?php
if (is_page('Home'))
{
	include(TEMPLATEPATH.'/header-col3-home.php');
}
elseif (is_page('Booking Procedure'))
{
	include(TEMPLATEPATH.'/header-col3.php');
}
elseif (is_page('Contact Us'))
{
	include(TEMPLATEPATH.'/header-col3-contact.php');
}
else {include(TEMPLATEPATH.'/header-main.php');}
?>
