Get a single specific image from Wordpress Media Library

Question

I've uploaded images to Wordpress Media Library.

I understand that I can view am image then get the URL for that specific image and then use the img html tag to display this on the page.

This however doesn't get the alt, title, caption and description of the image.

The img is not attached to a post or page field and so i assume you cannot use the Get Attachment function etc.

The reason I want to use a function instead of writing out a static img html code is so that they are cached better and easier to maintain with all data for the image been updated in the Media Library instead of having to edit html code which is not idea for the end user.

thank you in advance.

Answer 1

first get image

function get_images_from_media_library() {
    $args = array(
        'post_type' => 'attachment',
        'post_mime_type' =>'image',
        'post_status' => 'inherit',
        'posts_per_page' => 5,
        'orderby' => 'rand'
    );
    $query_images = new WP_Query( $args );
    $images = array();
    foreach ( $query_images->posts as $image) {
        $images[]= $image->guid;
    }
    return $images;
}

and display image

function display_images_from_media_library() {

    $imgs = get_images_from_media_library();
    $html = '<div id="media-gallery">';

    foreach($imgs as $img) {

        $html .= '<img src="' . $img . '" alt="" />';

    }

    $html .= '</div>';

    return $html;

}

and use php fire event

<?php echo display_images_from_media_library(); ?>

or use this function

<?php

if ( $attachments = get_children( array(
'post_type' => 'attachment',
'post_mime_type'=>'image',
'numberposts' => 1,
'post_status' => null,
'post_parent' => $post->ID
)));
foreach ($attachments as $attachment) {
echo wp_get_attachment_link( $attachment->ID, '' , true, false, 'Link to image attachment' );
}

?>
