通过在通话时指定图像的大小，您可以很容易地以多种大小显示特色图像，但如果您希望它们不同，可以使用此插件中的代码：

以下是教程：

e、 g.注册示例：
if (class_exists(\'MultiPostThumbnails\') {
if (MultiPostThumbnails::has_post_thumbnail(\'folio\', \'feature-image-2\')) {
MultiPostThumbnails::the_post_thumbnail(\'folio\', \'feature-image-2\');
}
if (MultiPostThumbnails::has_post_thumbnail(\'folio\', \'feature-image-3\')) {
MultiPostThumbnails::the_post_thumbnail(\'folio\', \'feature-image-3\');
}
if (MultiPostThumbnails::has_post_thumbnail(\'folio\', \'feature-image-3\')) {
MultiPostThumbnails::the_post_thumbnail(\'folio\', \'feature-image-3\');
}
}
示例用法：
<div id="slider">
<?php
// Checks if post has a feature image, grabs the feature-image and outputs that along with thumbnail SRC as a REL attribute
if (has_post_thumbnail()) { // checks if post has a featured image and then outputs it.
$image_id = get_post_thumbnail_id ($post->ID );
$image_thumb_url = wp_get_attachment_image_src( $image_id,\'small-thumb\');
$attr = array(
\'class\' => "folio-sample",
\'rel\' => $image_thumb_url[0], // REL attribute is used to show thumbnails in the Nivo slider, can be skipped if you don\'t want thumbs or using other slider
);
the_post_thumbnail (\'feature-image\', $attr);
}
if (class_exists(\'MultiPostThumbnails\')) {
// Loops through each feature image and grabs thumbnail URL
$i=1;
while ($i<=5) {
$image_name = \'feature-image-\'.$i; // sets image name as feature-image-1, feature-image-2 etc.
if (MultiPostThumbnails::has_post_thumbnail(\'folio\', $image_name)) {
$image_id = MultiPostThumbnails::get_post_thumbnail_id( \'folio\', $image_name, $post->ID ); // use the MultiPostThumbnails to get the image ID
$image_thumb_url = wp_get_attachment_image_src( $image_id,\'small-thumb\'); // define thumb src based on image ID
$image_feature_url = wp_get_attachment_image_src( $image_id,\'feature-image\' ); // define full size src based on image ID
$attr = array(
\'class\' => "folio-sample", // set custom class
\'rel\' => $image_thumb_url[0], // sets the url for the image thumbnails size
\'src\' => $image_feature_url[0], // sets the url for the full image size
);
// Use wp_get_attachment_image instead of standard MultiPostThumbnails to be able to tweak attributes
$image = wp_get_attachment_image( $image_id, \'feature-image\', false, $attr );
echo $image;
}
$i++;
}
}; // end if MultiPostThumbnails
?>
</div><!-- end #slider -->
