Media Library (Add, Insert, Edit, Delete & Settings)
Go to Media → Library to see every image, video, and document ever uploaded to your site. You can drag-and-drop files directly onto this screen, or upload while writing a post via the Image block.
Uploading and browsing media
Go to Media → Library to see every image, video, and document ever uploaded to your site. You can drag-and-drop files directly onto this screen, or upload while writing a post via the Image block.
The library shows file type, upload date, and which post (if any) each file is attached to — helpful for cleaning up unused files later.
Real-life example: The Media Library is a shared photo album for your whole website — once a picture is uploaded, any post or page can reuse it without re-uploading.
Inserting and editing media in content
While editing a post, add an Image block, click Upload/Media Library/Insert from URL, then pick or upload your file. After inserting, click the image to access alignment, size, and a basic crop/rotate editor.
Always fill in the Alt Text field for every image — it describes the image for screen readers and helps search engines understand your content.
<!-- Poor: -->
<img src="img1234.jpg" alt="image" />
<!-- Good: describes the actual content -->
<img src="wordpress-dashboard-screenshot.jpg"
alt="WordPress dashboard showing the Posts menu highlighted" />Deleting media and managing settings
Deleting a file from the Media Library permanently removes it from your server — WordPress will warn you if it is currently used inside a post or page.
Under Settings → Media, you control the pixel dimensions WordPress automatically generates for Thumbnail, Medium, and Large image sizes whenever you upload a photo.
- Media settings control auto-generated image sizes (thumbnail, medium, large)
- Deleting an in-use image can leave a broken image icon on your site — check first
- Organize media with descriptive filenames before upload (not IMG_2031.jpg)
