Attaching any unattached media files that you may have floating around is a good way to keep things organized and running smooth. Normally, when you're working on a post in the Edit Post screen, you click the Upload/Insert button and use the nifty drag-n-drop media uploader to get 'er done. When you upload your media files in this manner, WordPress "knows" that you want to attach the file to that particular post. Super straightforward sure, but there are situations where WordPress doesn't know which post to use. In this DigWP post, we walk through the process of finding unattached media files and attaching them to their respective posts.
