Change default image size on attachment pages

I’m looking for a similar answer. Rather than have WP limit the height of the image on the “linked to” page I would like to constrain the width or change the height setting to something else. Where do I find the code to change this?

“I should have searched for this before I started a new topic.“

Certainly a good practice for unresolved topics. (I closed your topic and pointed everyone here.)

Anyway, a solution…

Best option is to create a template specifically for attachments. WordPress makes this easy, as attachment.php is a default theme template. Here’s a quick way to accomplish what you want:

1. Copy single.php (from current theme) to attachment.php.

2. In attachment.php we’ll need to make one big modification, as it will not display the image attachment automatically. Just above:

<?php the_content(); ?>

or equivalent (from your theme), here’s what I have in my own attachment.php:

<?php $image_info = getimagesize($post->guid); ?>
<img src="<?php echo $post->guid; ?>" alt="<?php the_title(); ?>" title="<?php the_title(); ?>" <?php echo $image_info[3]; ?> />


Description of code:

First thing, it collects the image’s properties thanks to the PHP function getimagesize(). $post->guid is the record in a post which holds the URL for your attachment.

In the <p> element it displays the image (by echoing $post->guid) and provides proper alt, title, and the (again thanks to getimagesize()) height and width attributes.

Feel free to modify the code so it links directly to the image, etc. Since you have a separate template for attachments, you can also change anything else that’s displayed (I don’t list author info or provide comments in mine, for example).

You can pull the $image_info line and just use this to display the image:

<img src="<?php echo $post->guid; ?>" alt="<?php the_title(); ?>" title="<?php the_title(); ?>" />

Not as cool (as it lacks automation of the width and height attributes), but apparently your host restricts PHP functions like getimagesize() from working off of urls.

One more small question (I’m sure it’s easy for you PHP Wizards).

How do I link back to the original post from this neq picture page:

Hey, thanks Kafka — this was a perfect fix for me. Very nice to get such a useful response.

this seems like a great solution but i have a question. can you define the size of the image as well? my images are no longer shrunk down but now appear full size. i’d like to set the size to 400 wide, auto height.

thanks!
