Doesn’t work for me – I just get a blank screen – both for site and wp-admin. What could I being doing wrong? Followed your instructions perfectly.

Everything is done in a WP API. This is a function WP built in and is used in the default theme. It’ll take a lot of digging into the WP code to figure out which is way beyond my job description.

Any idea how to make transparency? It looks like Custom_Header.php converts to jpeg when it crops. Without cropping, however, it keeps the original file.

I thought it might be:

‘post_mime_type’ => ‘image/jpeg’,

but that code doesn’t do anything

so i think it might be

$file = wp_handle_upload($_FILES['import'], $overrides);

which overrides the original attribute of the file, but I can’t seem to change it to make it keep the original attributes.

I don’t think you could do it easily since the custom header is a core WP function. The API is kind of hijacking the header image outside of your theme. Although you could probably make a page template for a specific category and use a different header.php for it.

Thanks! This worked great! But now I want to have a different header for a specific category. How do I do that not that the custom header is defined in the functions.php?

Great Tutorial! I have made it work on my own demo theme (not on t’internet yet, on my PC’s test webserver).

It would be great if this worked for pictures in other locations on a theme…such as a middle or footer banner.

I’ve had a play but add_custom_image_header is WordPress defined and only works for the header…
