Try this, my function with the one from esmi inside

<?php

/* This function will run after the parents functions.php */
add_action( 'after_setup_theme', 'post_theme_setup' );

if ( !function_exists( 'post_theme_setup' ) ):

function post_theme_setup() {
   /* Code goes here! */

   add_filter( 'twentyten_header_image_width', 'my_header_width' );
   add_filter( 'twentyten_header_image_height', 'my_header_height' );
   function my_header_width($width) {
   	$width = 980;
	return $width;
   }
   function my_header_height($height) {
	$height = 224;
	return $height;
   }
}

endif;

Hi,
I have just had another look at the twenty eleven functions.php

The good news is the function ‘twentyeleven_setup’ is pluggable, dumb thing is I wrote about it back in April.

if ( ! function_exists( 'twentyeleven_setup' ) ):
function twentyeleven_setup() {
}
endif;

That means we can just copy the whole function from the parent to the child, we do not rename it, the childs function will run and the parents will not!

Copy lines 47 – 210 from the parent
From

/**
 * Tell WordPress to run twentyeleven_setup() when the 'after_setup_theme' hook is run.
 */
add_action( 'after_setup_theme', 'twentyeleven_setup' );

Down to the endif;

endif; // twentyeleven_setup

That function is now ours to change whatever we want!

That has opened up my thinking!

Glad I answered this one!

To answer the topic have a look at this plugin, read the information and test if possible.

—————————————————————
The additional image size is set in the themes functions.php

// Used for large feature (header) images.
add_image_size( 'large-feature', $custom_header_support['width'],$custom_header_support['height'], true );

// Used for featured posts if a large-feature doesn't exist.
add_image_size( 'small-feature', 500, 300 );

Do not edit any of the default themes files, if you are doing any modifications use a child theme.

Why is there is no core function to remove_image_size( ‘small-feature’ );

UNTESTED CODE:
So in a child themes functions.php

/**
 * Unset unwanted image sizes in child theme
 */
function dr_remove_image_size( $name ) {
	global $_wp_additional_image_sizes;
	unset( $_wp_additional_image_sizes[$name] );
}

function dr_unset_images(){
	dr_remove_image_size( 'small-feature' );
	/* Not using the header images */
	dr_remove_image_size( 'large-feature' );
}
add_action( 'after_setup_theme', 'dr_unset_images' );

I would just live with the images unless I had thousands of posts!

Hi,
If you are changing the header size in a child theme then it needs to be wrapped in a ‘post_theme_setup’ function, called with the ‘after_setup_theme’ hook!

WordPress will then load the childs functions.php, the parents functions.php and lastly the childs ‘after_setup_theme’ function hook.

add_action( 'after_setup_theme', 'post_theme_setup' );
if ( !function_exists( 'post_theme_setup' ) ):
function post_theme_setup() {
   /* Code goes here! */
}
endif;

The images will not be re-sized retrospectivly, the parents headers will always be smaller than the new ones, so you will upload new images.

I will leave it back with esmi!

@shahidkarimi,
Why are you asking questions in a topic from 8 months ago, if you have a question start a new topic!

There have been new releases in the last eight months with many issues resolved, so it is likly not a problem now!

Hi Guys,

'url' => '%s/

The %s is returning the parents directory and not the child themes directory, that is why the code is not working.

You need to upload a second set of smaller banner thumbnails that are 230 x 66.

If you want to use this code you must do as esmi said, image names should be lowercase, no spaces, and every header must have a thumbnail
storm.png and storm-thumbnail.png
storm-chaser.png and storm-chaser-thumbnail.png

width can be altered to display a bigger thumbnail if you want, height should be proportional, just re-size the headers 230px wide and save as with the -thumbnail added!

Making the thumbnails takes a few minutes and makes all the difference.

Maybe I can help out here, have a look at this code:
http://pastebin.com/56X9mX9R

First it will remove the parent themes images.

unregister_default_headers

Next there is a nice little function I created:

• it will look in the child theme’s folder for /images/headers/
• loop through the files
• find images with -thumbnail like storm-thumbnail.png
• load the images into an array, path, thumbnail, name etc:
• name is first cased storm-chaser becomes Storm Chaser for the title
• Register the new headers

It is really nice because you only need to add the headers and thumbnails to the folder, you do not have to write the code to register them the function will do all that for you!

This would make a nice addition to your functions library!

If you are using a cache plugin clear the cached pages.

Put a screen echo in both the files somewhere and see if they are loading!

If not review the code above!

<?php echo 'This is the category-news.php file!' ; ?>

<?php echo 'This is the post-news.php file!' ; ?>
