Use the Attachment Image!

Встановлення

To utilize this plugin, you will first need to upload use_attachment_image.php to the /wp-content/plugins/ directory on your web server; and activate the plugin through the ‘Plugins’ menu in WordPress.

Next, place <?php use_the_attachment_image() ?> (will include a link to the post), or <?php use_the_attachment_image_nolink() ?> (will NOT include a link to the post) in your template to include a thumbnail of the first attachment image. Note the function must be inside of a WordPress loop.

By default, this function will include a thumbnail image. To include images of different sizes, use the respective functions below. You may also use <?php use_the_attachment_image_nolink() ?> in place of <?php use_the_attachment_image() ?> here.

Thumbnail <?php use_the_attachment_image('thumbnail'); ?>
Medium <?php use_the_attachment_image('medium'); ?></p>
Large <?php use_the_attachment_image('large'); ?></p>
Full <?php use_the_attachment_image('full'); ?>
20 px <?php use_the_attachment_image(array(20,20)); ?>
Feel free to replace 20px with another specific size to best meet your needs. Note that WordPress will scale a larger image down to give you the size you desire here.

It is possible to include a thumbnail image from each post in your RSS feed. To do this, simply add this code to your theme’s functions.php file. From cd harrison.

<?php
if (function_exists('use_the_attachment_image')) {
    function insertAttachmentRSS($content) {
        global $post;
        { $content = use_the_attachment_image() . $content; }
        return $content;
    }
    add_filter('the_excerpt_rss', 'insertAttachmentRSS');
    add_filter('the_content_feed', 'insertAttachmentRSS');
}
?>
