Steps to verify
- Read the source image URL.
- Check public response conditions.
- Compare the platform’s display.
How to interpret the result
Cookie-dependent or expiring images can fail for other requests. Visibility in your browser alone does not prove public access.
Deciding what to do next
Use a stable public path for distribution imagery. Record inspection time and access conditions for failures.
Feature scope
Inspect HTML Open Graph and Twitter/X fields and approximate a card, without clearing platform caches or guaranteeing every platform’s rendering.
Frequently asked questions
Does the preview prove all platforms show the image?
Platform requests, caches and support differ, requiring separate checks.
