Are captions stored anywhere?

1. Yes, it stores the caption in it’s own place in the DB. I can’t quote the exact location but in WordPress, “Attachments” are a post type and it stores each attachment just like a post. For an attachment post type, it treats the Image Caption as the_excerpt the Image Description as the_content and the Image Title as… the_title.

2. where $post_id is the current post, this code will output all the attachments of a post, and their titles descriptions and captions

   $q = new WP_Query( array(
       'post_parent' => $post_id,
       'post_type' => 'attachment'
   ));
   if($q->have_posts()){
       while($q->have_posts()){
           $q->the_post();
           ?>
           <h3><?php the_title(); ?></h3>
           <?php
   
           if ( wp_attachment_is_image( $post->id ) ) {
               $att_image = wp_get_attachment_image_src( $post->id, "large");
               ?>
   <img src="<?php echo $att_image[0];?>" width="<?php echo $att_image[1];?>" height="<?php echo $att_image[2];?>"  class="attachment-large" alt="<?php $post->post_excerpt; ?>" />
               <?php
           }
   
           // caption
           the_excerpt();
   
           // description
           the_content();
       }
   }
   wp_reset_query();
   

   Attachments are all children of the post they are attached to, and you can use this to do your own custom gallery code. They also have a lot of data in their custom fields, such as image dimensions, EXIF data, etc They can even be commented on.

   You can take the code from the inner loop and place it in attachment.php in your theme, just double check I haven’t made any syntax typos before you do.
