I wish to set a featured/header image for each of my category archive pages, how would I go about doing this without hard coding each category into the theme?

An example of the page is at http://keswickscouts.org/section/cubs

The code form header.php is

            <div id="main-image">
            // Check to see if the header image has been removed
            $header_image = get_header_image();
            if ( ! empty( $header_image ) ) :
            <a href="<?php echo esc_url( home_url( '/' ) ); ?>">
                    if ( !is_404() && !is_attachment() ) { // Check if this is not 404 or attachment page
                        // Check if this is a post or page, if it has a post-thumbnail
                        if ( is_singular() && has_post_thumbnail( $post->ID ) && ( $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'post-thumbnail' ) ) && $image[1] >= HEADER_IMAGE_WIDTH ) :
                        echo get_the_post_thumbnail( $post->ID, 'post-thumbnail' );
                    else : ?>
                        <img src="<?php header_image(); ?>" height="<?php echo get_custom_header()->height; ?>" width="<?php echo get_custom_header()->width; ?>" alt="" />
                <?php endif; } // end check for featured image or standard header ?>
        <?php endif; // end check for removed header image ?>
        </div><!-- end #main-image -->

What is the question? – s_ha_dum Nov 6 '12 at 14:55
I'm seeing an issue where the "post-thumbnail" image size is probably not going to be as wide as the HEADER_IMAGE_WIDTH (I'd change it to 'full') but otherwise I'm not sure what you're asking. – guiniveretoo Nov 6 '12 at 15:34
You also might want to check the code for your 404 page - it says "use the search box above" but there's no search box! – guiniveretoo Nov 6 '12 at 15:36
I've reworded the question, hopefully it should make more sense. I've had no issues with the width but will have a look, and thanks for the heads up on the 404 page it is completely knackered – The-Keswickian Nov 6 '12 at 18:43

What I did was; using the Taxonomy Images plugin to associate an image with each category, then to my theme's header.php, below the <a> line in the above code;

            $image_id = apply_filters( 'taxonomy-images-queried-term-image-id', 0 );
            if ( is_category() && ! empty( $image_id )):
             print apply_filters( 'taxonomy-images-queried-term-image', '',  
                'image_size' => 'header'
            ) );
            else : ?>

And add <?php endif; ?> below the endif 'end check for featured...'

and defined the header image size in functions.php with

add_image_size( 'header', 960, 260, true );

How can I modify this to work on single.php? Just removing the if ( is_category() ) doesn't work. – Rev Jul 23 '13 at 18:14
