Comment:

 attachment:22960.diff provides utility functions to get all image srcs in
 post_content and / or images attached to the post plus image src(s) from
 gallery shortcode(s)

 Introduces `get_content_images( &$content, $remove = false )` which will
 assemble `[gallery]`s and read `<img>`s, extract their srcs, optionally
 remove them from the content, and return them in a unique array.

 Introduces `get_the_images()` which assembles a unique list of every image
 in the post's content retrieved via `get_content_images()` + all of the
 images attached to the post, displayed or not

 Introduces `get_post_images()` which retrieves WP_Post objects for all
 images attached to the post


 If more or different functionality is needed / wanted, let's iterate!
