header image – where

go to your ‘header.php’ file and look for this line

/* BEGIN IMAGE CSS */

everything after that will give the information & instructions for header images in that particular theme.

1. Modifying the default… is a challenge even for experienced users.
2. The code quoted by marianne was in earlier versions of the theme.
3. What happens if you make your image exactly the same size as the original header and you upload it by ftp to the proper location with the same name – overwriting or previously renaming the original kubrick header?
4. DON’T edit themes online – there is undo button!

if i just knew the path or the acutal file name
THAT’s the actual file name: kubrickheader.jpg – you are talking about all the time.

I am afraid you don’t read the replies, do you?
What I suggested above does NOT require any editing of any file.
Just plain normal usage of a FTP client which is MUST if you have and want to have a website.

Then lets’ get back to the basics.
The image file is NOT in any .php files. It is just sitting there in the wp-content/themes/default/images folder.

As EVERYTHING related to style – it is called from the style.css, as a background image.
(I told you not to mess with the default…)

Usually, the images for a theme are located in
wp-content/themes/theme-name/images/ directory

Did you try to look around on your server with any of the FTP_Clients as it was suggested? If no FTP – no changes to your theme’s images. Period.

I was (am) having the same problem as marley1. When following the tutorial as written here, it says “To change the image file, replace the “kubrickheader.jpg” with the name of the new graphic image you have uploaded to your site to replace it.”

This is incredibly confusing, as not only does the code it is referencing (directly above this quote) not appear in the header.php template, nor does the “kubrickheader.jpg”.

I had the same problem, trying to change the colors in the gradient page header in the default theme, and here’s how I solved it:
(first my setup:
OS: Ubuntu jeOS 8.04.1 (virtual machine minimal install), Webserver: Apache 2.2.8, PHP: 5.2.4)

1. PHP5 must include the GD library. I downloaded and installed into Ubuntu with sudo apt-get install php5-gd It was not available by default.
2. The jpg file (MichaelH is correct about the location of the file in his post above this one) has to be world writable, or at least writable by the Apache user (on my machine that’s www-user). The easiest way to do that is follow the official directions in the detailed instructions on permissions here. What I did was, from the console change to the blog root directory and type chmod -Rv 0777 ./wp-content I do not believe this constitutes a security risk, but if you’re worried, change the permissions back to 0755 after you’ve changed the jpg.
3. The standard install of PHP5 defaults to 16M of memory for scripts. To change the header jpg, I set the memory to 256M in php.ini.memory_limit = 256M Note that I didn’t test too finely, but 128MB did not seem to work. I am going to change the memory back to a more sane amount now that the jpg has been modified.
4. Restart Apache and you’re good to go.

I have no idea how those steps would be accomplished with a hosting provider, but that’s what I had to do with a default installation of Ubuntu 8.04 JeOS (that’s the virtual server minimal installation). I hope this helps someone. I see by searching the forums here this is not an isolated problem. It would be good if somewhere WP indicated that the GD libraries are required and that the standard script memory setting is too low.

Good luck!
