have copied the functions.php folder from twenty ten and into my new theme folder.
And that’s where you went wrong. You must start with a blank functions.php file in your child theme and then only add your amended or custom functions.

Thank for the quick reply;
I have followed the video from Lynda.com but will not work.
Here is what is in my function.php now. Could you advise on what I need to add or remove. I have been at this literally all day and am getting no where.
I really appreciate your help.

I have placed a style.css in that folder with all of the appropriate css. (the sheet is also imported from the twent tenty theme).
Can you also elaborate on what you mean by “imported”? You didn’t copy all of the parent’s CSS into the child, did you?

No sorry my error I have the code @import url(‘../twentyten/style.css’); at the top of my style sheet. Then below it I have all of the styles that I want to change. I don’t think that is my issue. If I drag my functions.php out of my theme folder and on to my desktop it works perfect. I could create a different image for each pages header but the size is no good. If I drag functions.php back, the size is good but I am stuck with whatever I have chosen for my header image and can not assign a featured image on each page?
Thanks

OK – start with a blank functions.php file and add:
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;
}

No Dice?
I created a new functions.php and added the following per your instructions:
<?php
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;
}
?>
The size is good but am still unable to change header images using the featured image option?
Shep
Are you using images that are 980px by 224px?

Good Morning Esmi;
First of all I want to thank you for working with me. I truly do appreciate it.
Yes the header images that I am trying to use as a featured image on a page is 980 X 224.
I spent another 3 or 4 hours last night trying to figure it out with no luck.
Move the functions.php out of the themes folder and you can have a different header picture (set as featured image) on each page but the size is wrong. Put the functions.php back into the themes folder and the size is perfect but you can no longer change images. You are stuck with the single header image that you gave chosen in headers.
What version of WordPress are you using?
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!

Hi Shepme,
I am having the exact same issue with my Lynda tutorial, it has stumped me and now I am stuck trying to figure out this function so I can keep on moving forward!
Unfortunately the trainer on Lynda is using a slightly different version of the TwentyTen theme and that’s where the issue lies im guessing. So much for streamlined learning!
Hoping to see a resolution shortly.
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 David;
Thanks for the input. I will try what you have suggested.
Can you please advise exactly were I place this inside of the header.php.
Thanks

Good Day, Muchogaucho:
Yes, I have found the same thing with the “creating child themes” using Lynda.com. Many of the steps Morten (the instructor) shows the viewer to do on a php document is different than the actual php document that you open so it is a bit confusing were to place certain things. It take a couple of tries.
I have been designing websites for the past 2 or 3 years and have always wanted to learn how to create sites in wordpress that the person whom you are building it for could go in and alter the pages without getting into the html/css.
I was disappointed to learn that to customize wordpress you have to know PHP. I thought there would be a css page and an html page for each page and you build it using those two things with maybe some Javascript thrown in.
It appears if I want to pursue the wordpress thing I must first learn PHP.
What are your feelings?

@sheme and @muchogaucho
If you have been adding this code in the header.php then you are off track, the code goes in the child theme, if you do not have a functions.php then you must create one and add the code!
It could be your lucky day, I posted a Video on YouTube yesterday that does most of what you want it adjusts the header height, removed the default headers,however adjusting the width means also adjusting the styles.css
Here is the YouTube Video
There is a whole series of posts (Over 20 Sessions) on my website for beginners, with the twenty ten theme, these are now old but they might help you get a base understanding!
The posts have download child themes, there is also a downloads page, and it is all free!
Please do watch the Video and take in the instruction, that is the way you will learn, rather than just downloading the child themes.
