How to query details of images in gallery that is attached to a post

Question

I have several images attached to each post. I need to generate a gallery, but because it's heavily customized I don't want to use a gallery plugin, nor the gallery short code. It's also situated in a DIV that is totally separated from the post content/title etc. so it has to be stand-alone code in PHP, hard-coded.

Basically if there's a method to retrieve the list of attachments in a URL format.. and then pull in the proper sizes (filename_80X80.jpg or something along those lines - I know the filenames are manipulated after the thumbnail size).

I already have the thumbnail sizes covered using

add_image_size( 'ourwork_full', 589, 315, true );
add_image_size( 'ourwork_thumb', 80, 80, true );

in the funtions.php file of the template.

How can I achieve this? Do I need to use custom WP query? Or is there a function/template tag that I am missing?

Answer 1

Query for image attachments would be something like this (taken from Get The Image plugin/extension) with get_children():

$attachments = get_children( array( 
    'post_parent' => $args['post_id'], 
    'post_status' => 'inherit', 
    'post_type' => 'attachment', 
    'post_mime_type' => 'image', 
    'order' => 'ASC', 
    'orderby' => 'menu_order ID' 
) );

Then you can loop through array and retrieve URLs with wp_get_attachment_image_src() which will get you URL and dimensions.
