Get medium image size in WordPress

This is for everyone who’s been trying to find out how to get the medium image size of a post attachment in WordPress:

You’ve got to send the function the ID you’re trying to get the medium images for.

$medium = wp_get_attachment_image_src($picture->ID, 'medium', false);
$med_url = $medium[0];
$med_width = $medium[1];
$med_height = $medium[2];

There are a lot more things you can find out by analyzing wp-includes/gallery.php.

Thank you so much. This is really helpful.

Additionally I use the customfield for my image name and to find the image ID use an SQL like

$imageID=”SELECT * FROM `wp_posts` WHERE guid=’http://www.site.com/wp-content/uploads/$image[0]'”;

Then I use your code and life is good ­čÖé

Thanks again…

Hello,
This is very useful, thanks!

I was wondering if it’s possible to get medium size of an attachement if I don’t know $picture->ID, but rather url of attachment.

Thanks.

Right on, thanks for this one.┬á Very helpful and smart to reduce the image file size instead of just hard-coding the large image’s width to be the smaller dimension.
