 * Try changing this line:
 * `if ($thumb == NULL) { echo ''.$nothumb.'/images/defaultthumb.jpg'; } else { 
   echo $thumb; }`
 * To this:
 * `if (! $thumb) { echo ' ' . $nothumb . '/images/defaultthumb.jpg'; } else { echo
   $thumb; }`

 * One more thing to change, in your dp_attachment_image() function. Change:
 *     ```
       if ($images = get_children(array(
       		'post_parent' => $postid,
       		'post_type' => 'attachment',
       		'numberposts' => 1,
       		'post_mime_type' => 'image',)))
       		foreach($images as $image) {
       			$attachment=wp_get_attachment_image_src($image->ID, $size);
       			?><img src="<?php echo $attachment[0]; ?>" <?php echo $attributes; ?> /><?php
       		}
       }
       ```
   
 * To this:
 *     ```
       $images = get_children(array(
       		'post_parent' => $postid,
       		'post_type' => 'attachment',
       		'numberposts' => 1,
       		'post_mime_type' => 'image'));
       if ($images)
       		foreach($images as $image) {
       			$attachment=wp_get_attachment_image_src($image->ID, $size);
       			?><img src="<?php echo $attachment[0]; ?>" <?php echo $attributes; ?> /><?php
       		}
       }
       ```

   try a few things, but it will be a few days before I can get back to you with
   anything.

 * OK, I’ve got it. Replace the following:
 * `<img src="<?php echo $attachment[0]; ?>" <?php echo $attributes; ?> />`
 * With:
 * `<img src="<?php echo $attachment[0]; ?>" width="<?php echo $attachment[1]; ?
   >" height="<?php echo $attachment[2]; ?>" />`
 * According to what’s in the WordPress documentation for the wp_get_attachment_image_src()
   function, that should work. Let me know if it helps!
