A project at work needed me to write a UI to find and delete duplicate attachments on a single post, from a client’s WordPress website. Creating a couple of queries where I could look over each post in turn, and check a hash for each file attached, then spot the duplicate hashes wasn’t too hard.

, are just not that easy to distinguish from other hashes, e.g. dbe0256fe35b88ebd4e4e433604b7487
