Re: WordPress: Separating images/content from the_content()

[TheDoc]

Is it one image or multiple?

If it is a single image then you’ll want to use the featured image function. Check out post_thumbnail. It’s a truly wonderful thing. Here’s an example of what you would put in your functions.php file:

// add post-thumbnail functionality

if (function_exists('add_theme_support')) { add_theme_support('post-thumbnails'); }

set_post_thumbnail_size( 100, 100, true ); // Normal post thumbnails

add_image_size( 'custom-1', 125, 125, true ); // Custom size that will crop the image to fit the proportion

add_image_size( 'custom-2', 255, 236, false ); // Default is false, "soft proportional crop"

If it’s multiple images, you can do that too! You’ll need to run a loop on images that have been attached to the page/post. When you’re editing a page and you upload images for insertion, those images become ‘attached’ to the page. So, instead of actually inserting them onto the page, you can just run a loop through all of the attachments!

To give you an idea of how to do this, this is some code that I used when I needed to put all of the images into a lightbox, but I only wanted to use the single thumbnail. This will output blank links of all of the attached images:

$args = array(

'order'          => 'ASC',

'post_type'      => 'attachment', // important - will only loop through attachments

'post_parent'    => $post->ID,

'post_mime_type' => 'image', // attachment type

'post_status'    => null,

'numberposts'    => -1 // infinite results

);

$attachments = get_posts($args);

if ($attachments) {

foreach ($attachments as $attachment) {

$atturl   = wp_get_attachment_url($attachment->ID); ?>



" class="lightbox" rel="portfolio" title="">


}

?>
