in the header.php look for code to call the image and use the code below:
<a href="<?php bloginfo('url'); ?>" title="Home">insert your code for your image</a>
about the vertical line, check your style.css and look for border-left and border-right properties and try to remove them.
open your rotating_images.php, replace code below:
<img src="<?php bloginfo('template_url'); ?>/headers/header_<?php echo $random_image; ?>.jpg" alt="Click here to return to the home page!" />
with this one:
<a href="<?php bloginfo('url'); ?>" title="Home">
<img src="<?php bloginfo('template_url'); ?>/headers/header_<?php echo $random_image; ?>.jpg" alt="Click here to return to the home page!"/> </a>
then log in to your webhost cpanel then to the file manager, upload your edited rotating_images.php exactly the same directory ok?
