I have a MU network setup and I'm pulling in media library images and displaying 4 of those images randomly from across the entire network.

I've seen a few people on here using similar codes to do the same thing, my questions is:

How do I crop images pulled directly from the media library dynamically?

Currently the code works however it merely scales the image size and on right click > view image it shows the image in full size and not as a cropped thumbnail etc.

This obviously boosts the page size if each image is 5mb (x4 = 20mb) which is unnecessary, here is the code:

function get_images_from_media_library() {
    $args = array(
        'post_type' => 'attachment',
        'post_mime_type' =>'image',
        'post_status' => 'inherit',
        'posts_per_page' => 4,
        'orderby' => 'rand'
        );
    $query_images = new WP_Query( $args );
    $images = array();
    foreach ( $query_images->posts as $image) {
        $images[]= $image->guid;
    }
    return $images;
}

function display_images_from_media_library() {
    $imgs = get_images_from_media_library();
    $html = '<div id="media-gallery">';
    $html .= '<h3>Oriel / Gallery</h3>';
    foreach($imgs as $img) {
        $html .= '<img src="' . $img . '"/>';
    }
    $html .= '<h4><a href="' . get_site_url() . '/gallery">Weld mwy o / View more <i class="fa fa-chevron-right"></i></a></h4>';
    $html .= '</div>';
    return $html;
}

Any help or suggestions would be much appreciated.

You could try

$images[]= wp_get_attachment_image_src($image->ID, 'thumbnail')

Or define a new image size in functions.php

add_image_size()

  • Thanks for the response, I attempted using add_image_size() however it wasn't cropping it, the code pulls the images straight from the image library and not a post or page, I'm assuming that's why it's not able to crop it. I also attempted the first option, just returns the array however I'll play with that more and see if I can get something to come out cropped. – whst Dec 17 '13 at 14:14
  • Have you tried thumbnail? I don't use multisite much; the size could be being defined in the wrong place if mutisite uses themes differently. Also, have you flushed your image sizes? when you add a new size you'll need to regenerate all images on the site, this plugin is useful for that: wordpress.org/plugins/force-regenerate-thumbnails – Gaffen Dec 17 '13 at 14:17
  • Yeah I'm purging and regenerating the thumbnails as I go but there doesn't seem to be a way to do this using the standard thumbnails and image_sizes. <?php echo display_images_from_media_library(); ?> That's currently how I'm calling the code I posted above – whst Dec 17 '13 at 14:58
