set image size on attachment page

[mmjaeger]

Hello
I'd like to use a different image size on the attachment page - it looks like WP/Genesis is taking the medium image - how can I do that?

Thanks

Hello,

Good question. I had to dig around WordPress to find out exactly where this was being specified. You can adjust this with the WordPress '' filter. Hereis what I came up with;

I hope this helps.

Thank you! I tried it and it works perfectly!

This problem has been driving me nuts for ages - finally took the time to search for an answer. I'm off to paste this into a bunch of sites! Thank you so much!

This looks like the fix I'm looking for. However, I pasted into the bottom of functions.php of the Minimum Pro theme and it disabled the whole file. Do I need to create a seperate attachment.php file to add to the Child Theme?

Or is it something with the //* -tags

I'm trying to use it in conjuction withe these styling options for the attachment pages:

//* Customize the post info function
add_filter( 'genesis_post_info', 'sp_post_info_filter' );
function sp_post_info_filter($post_info) {
if ( !is_attachment() ) {
	$post_info = '[post_date] by [post_author_posts_link] [post_comments] [post_edit]';
	return $post_info;
}}

//* Customize the post meta function
add_filter( 'genesis_post_meta', 'sp_post_meta_filter' );
function sp_post_meta_filter($post_meta) {
if ( !is_attachment() ) {
	$post_meta = '[post_categories before="Filed Under: "] [post_tags before="Tagged: "]';
	return $post_meta;
}}

Change //* to just //

The //* is expecting a */ closure.

I had to comment out the following, and then it worked;

add_filter( 'prepend_attachment', 'custom_prepend_attachment' );

// * Callback for WordPress 'prepend_attachment' filter.
// * 
// * Change the attachment page image size to 'full'
// * 
// * @package WordPress
// * @category Attachment
// * @see wp-includes/post-template.php
// * 
// * @param string $attachment_content the attachment html
// * @return string $attachment_content the attachment html

function custom_prepend_attachment( $attachment_content ){
        
        // set the attachment image size to 'full'
        $attachment_content = sprintf( '<p>%s</p>', wp_get_attachment_link(0, 'full', false) );
        
        // return the attachment content
        return $attachment_content;
        
}

Is that okay?
Can I also add some code here to prevent the image to link any further. See: http://www.thomaselshuis.nl/wpsite/portfolio/travelogue/attachment/gr-twilight-horizon/

Thanks!

Bart,

It will not hurt anything. Good luck.
