Quickly delete all attached images in Wordpress post
===

Apologies if this is a repeat question, I can't seem to find any answer to it. I have about 100 or so images attached to a specific wordpress blog post. I'm using a custom get_children call to pull all those images into a gallery. Just got word from the client that all those images need to be removed and changed to other images. The only way I know how to remove them is one by one in the add media modal. (You have to click show, then delete, then confirm)

Doing this one by one for 100 images is super time consuming. Does Wordpress have any faster way of doing this?
