Media Library »Unattached Files
When viewing your blog’s Media Library (Media → Library), there is a filter that shows your Unattached files.
If you click on the Unattached link, all of the media files not associated with a post or page (i.e. you did not upload them from within a post or page) will be displayed. Attaching files (images, specifically) to a post is not always necessary, although some themes use attached images for slideshows or other theme-specific features.
Clicking the Attach link will start the process of attaching the file to a post or page.
You can also attach multiple files at once: check the box next to each file name that you would like to attach, then select the Attach to a post option in the Bulk Actions drop down menu, and finally click the Apply button. This will only work if all the files selected are unattached.
When attaching items, this screen will pop-up:
First, type some text into the search box, select either Posts or Pages, and click the Search button.
Then, click the radio button next to the post or page you would like to attach the files to, and then click the Select button.
You will then be returned to your Unattached file listing and receive the following message, letting you know that the reattachment was successful.
- It’s not possible to un-attach an image from a post or a page. If you’d like to use the attached image with another post, please try uploading it again directly from the Media Library. Please note that the newly uploaded image’s URL will be different.
- It’s only possible to attach items that are unattached. It’s not possible to attach one image to multiple posts or pages.
