Question

When we simply want to show an image defined by a custom field (say “feature-image”) we’d use:

<img src="<?php echo get_post_meta($post->ID, 'feature-image', true); ?>" />

And now lets consider that due to my media settings, two more sizes of the same image above are created — 310×150 and 150×75 pixels each. How do I call them? (I mean, code for each image — I want to call each image size separately.) Is there a code similar to above that could use?

PS: I’ve noticed that questions requiring some code are being asked here on SO, and not WP.SE (at least not always). So, I thought it would be better to ask mine here as well.

Answer 1

If you know the image sizes you want, then you can use

wp_get_attachment_image( $attachment_id, $size, $icon, $attr );

You will of course have to find the attachment id to call wp_get_attachment_image.
