I’ve got my custom header working! Now, please, how do I change the admin page comments? It’s hard to narrow down which function to hook into. I’m talking about the text within the _e(‘mytext’) arguments. There seems to be no way to substitute that text with something else. I’ve googled this to death, and I’m no doubt missing something.

No, it states to put it in your theme’s functions.php file. If your theme doesn’t have a #header div, use the one your theme has.

Isn’t this article only half finished? You’ve not said how to actually place it in your theme?

I upload an image and nothing happens. I’ve tried adding a #header div and a #headerimg div to my theme where I want the picture but still nothing happens.

Did you try it? The example was a jpg only because the original header was a jpg.

Hi, quick question. How can I make it to support other image format (i.e. gif, png, etc)?

Seems like it only produce .jpg and I need it to be a transparent background image.

Thanks in advance!

Is this possible?
Custom header height decided by user in theme options?

define(‘HEADER_IMAGE_HEIGHT’, $theme_header_height);

and then create a input field on the theme options page?

here is my functions code: http://norsurf.pastebin.com/8ddqPG1H

Thank you! This worked great. I used it in Thesis. The important thing is to insert the URL for the header image into the applicable place in the code. Also rename the theme to your theme name. For thesis, I used thesis_16. Put the image dimensions in, and that’s it. You find the manage header option now in admin under appearance. Awesome code. Thanks!

Thanks for the reply.

I looked into wp-admin/custom-header.php and it looks like it’s happening on the crop. So I tested uploading a png with the correct size and sure enough it maintains its png/transparency.

I can’t figure out what to edit in custom-header.php though.

I do see under function step_3 is:

‘post_mime_type’ => ‘image/jpeg’,

which i tried editing to say “$type” or “image/png” or “png”, but nothing changes it still converts to a .jpeg, even when elimanate that string entirely. Somewhere is a function that converts but I can’t read the php code that gives it away.

At least I can make a tutorial or a notes page to instruct people to crop it to the default size prior to the upload.

The custom header API that you’re hooking into with this code is in the core. So that conversion is core, not in the code above.

Question:

Can this be edited so that when a user uploads a png with transparency it will maintain a png and thus its transparency?

Right now, it automatically converts to jpeg and turns the background black.
