Open the media item and copy its File URL.
Step by Step
- Sign in to WordPress admin.
- Open Media → Library.
- Select the image or file.
- Find File URL or Copy URL to clipboard.
- Copy and test the URL.
If That Doesn't Work
- A CDN or optimization plugin may serve visitors a different URL while WordPress still stores the original attachment URL.
- Changing domains may require updating old media URLs.
