Create a custom post type for a photo post

Question

I am looking for a way to create a Photo Post type. Basically a post that is a title and a single image. Where I am getting stuck is the actual attaching an image to a post. I would like to have an image upload field in a metabox. I followed this guide. I am able to see the WP upload box and I upload an image from my machine and click "Insert into Post". Then I publish the post. I don't know if the image is actually attached to that post though. I see the post in the database as well as the image as an "attachment" post_type.

Is this a good direction to go in if all I want is a simple attach a single image to a post along with a title?

Also, is there any way to simplify the media upload lightbox just for a certain post type? (Making it so the user doesn't need to know to click "Insert into Post" instead of "Save All Changes"?

Answer 1

If you want just a title and an image I suggest you put this argument when registering the custom post type -> 'supports' => array( 'title', 'thumbnail' ),

Answer 2

In your functions.php... The size are relative... you can use your same size container and align the image to the left if it's the case...

 if ( function_exists( 'add_image_size' ) ) { 
   add_image_size( 'post-photos', 900, 800);
 }

Custom Post Template

 <?php if(has_post_thumbnail()): ?>
   <?php the_post_thumbnail('post-photos', array('class' => 'post-photos-image')); ?>
 <?php endif; ?>

If using lightbox and you need to assign the ligtbox class to the image:

In your post template into the loop

 <?php
    $url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
 ?>
  <?php if($url !="") { ?>
      <img src="<?php echo $url; ?>" class="LIGHT-BOX CLASS">
  <?php } else {?>
               <!--Do not display image tag if there is none image attached-->
   <?php } ?>
