greater flexibility in targeting images attached to page

Question

Right now I have several images attached to my page, but I only want four of them to display in a slideshow, and then the other ones are referenced within the page's visual/html box. The problem is currently all my images attached to the page have a post type of "attachment", and this code iterates through all of them:

    <?php if ( have_posts() ) : while ( have_posts() ) : the_post();

    $args = array(
     'post_type' => 'attachment',
     'numberposts' => -1,
     'orderby'=> 'menu_order',
     'order' => 'ASC',
     'post_mime_type' => 'image',
     'post_status' => null,
     'post_parent' => $post->ID
    );

     $attachments = get_posts( $args );
      if ( $attachments ) {
       foreach ( $attachments as $attachment ) {
        echo wp_get_attachment_image($attachment->ID , 'full','',array('rel' => $attachment->post_name));
       }
      }
    endwhile; endif; ?>

My question is how can I distinguish the attachments so that it only queries some of them? For example, I tried adding the post_name attribute to the $args array but that didn't do anything.

Second, when I add img tag to the visual/html content editor, and then I add a src attribute, and then I go into the visual content editor, I want a non-programmer to click on the img box, which prompts them to edit the image, and then under source it is requiring them to add the full url path, and I dont think that's intutive to a non-programmer. Is there an easier way for them to add image via content editor?

Answer 1

Every file that is uploaded in WordPress is an Attachment, which is a kind of post ('post_type' => 'attachment').

When the file is uploaded inside a Post or Page, it is attached to that particular post/page ('post_parent' => $post->ID).

I can think of a solution that doesn't involves any particular coding:

• you simply have to put an order in your gallery images ('orderby'=> 'menu_order') and set the number of posts (of the attachment type) to be grabbed as four ('numberposts' => 4). ^{image source}

Answer 2

Add a meta box to the attachment edit screen and use get_post_meta() to separate the images you want from the rest.
