To update the image Facebook shows for a redirected link, make sure the page at the redirect’s final destination serves the right Open Graph tags, then submit the exact shared URL to Facebook’s Sharing Debugger and select “Scrape Again.” If the old image still appears even though the tags are right, give the image a new URL, update og:image, and request another scrape. A refreshed scrape is not a guarantee that every existing post attachment will change.
1. Check where the shared URL redirects
Start with the exact URL people share—not only the final page URL. Follow its redirect and confirm that it lands on the page you intend Facebook to represent. If it ends at an old page, the wrong locale, a login screen, or another unexpected destination, fix the redirect before refreshing Facebook’s data.

Then inspect the HTML returned by the destination page. The Open Graph protocol defines og:image as the URL of an image representing the page and og:url as the page’s canonical URL and permanent graph identity. The protocol also specifies the basic properties og:title, og:type, og:image, and og:url, placed in the document head. See the Open Graph protocol.

#1 Best Overall
<meta property="og:title" content="Page title">
<meta property="og:type" content="website">
<meta property="og:image" content="https://example.com/images/share-image-v2.jpg">
<meta property="og:url" content="https://example.com/current-page">Replace the example values with your real title, page type, image URL, and canonical URL. The image URL must point to the intended image, and the canonical URL should express which URL you want associated with the page. Don’t assume that changing the redirect alone changes the metadata Facebook has already fetched.
2. Request a fresh scrape of the exact shared URL
- Open Facebook’s Sharing Debugger.
- Enter the full URL people share, including its path and relevant query string, rather than entering only the redirect destination.
- Inspect the URL and metadata shown in the result. Confirm the redirect ends at the expected page and that the fetched Open Graph values include the intended image.
- After correcting the live page or redirect if needed, select “Scrape Again” to ask Facebook to fetch the URL again.
Secondary troubleshooting guides recommend requesting another scrape after correcting the tags. They also recommend checking the debugger’s result to catch a redirect to the wrong page or metadata that remains stale. A new scrape refreshes what Facebook fetches for a URL; it does not necessarily replace the preview attachment on a link already published in a post, nor does it guarantee that every Facebook surface updates immediately.

3. If the old image still appears
Confirm the fetched tags first
Run the exact shared URL through the debugger again and check which og:image it reports. If it still shows the old image URL, fix the page output, clear any relevant publishing or page cache, and request another scrape. Check that the destination’s HTML actually contains the updated tags—not just that a CMS settings screen has been changed.

If the debugger shows the correct og:image URL but Facebook continues showing old pixels, publish the desired image under a new URL, update og:image to that URL, and request another scrape. A secondary troubleshooting guide recommends this approach when the image file at the same URL has been replaced but the earlier image persists.
Rank #3
Check duplicate image tags and their order
If the page has several og:image tags, inspect their order and associated image properties. The Open Graph protocol says the first repeated tag, from top to bottom, is preferred when values conflict. Put the intended image first. This is protocol-level precedence guidance, not a guarantee about every detail of Facebook’s implementation.
The protocol also defines optional properties such as og:image:width, og:image:height, and og:image:alt. The alt value should describe the image rather than serve as a caption. These properties add metadata; they do not, by themselves, force Facebook to refresh a cached image.
4. Troubleshoot by symptom
| What you see | Likely issue to check | What to do |
|---|---|---|
| The debugger ends at an unexpected URL | The shared URL redirects to the wrong destination or an unintended page variant. | Correct the redirect, then confirm the final page serves the intended Open Graph tags. Debug the exact URL people share again. |
| The debugger shows the old image URL | The destination page still returns old or duplicate metadata, or a site cache is serving outdated HTML. | Inspect the rendered page head, correct og:image, check tag order, and request another scrape. |
| The debugger shows the new image URL, but the old image remains visible | The image was replaced at the same URL and an older image may still be associated with that URL. | Use a new image URL, update og:image, and scrape again. |
| A post already published still has the old attachment | Refreshing data fetched for the URL is distinct from changing an attachment already present in a post. | Do not assume the existing attachment will be rewritten by a fresh scrape. The available troubleshooting guidance does not establish that it will update automatically. |
Or skip the browser setup
If you also need a clean screenshot of the destination page while checking its visible result, ScreenshotNeo can return a screenshot or PDF from one API request. For example, this cURL command saves a WebP screenshot:
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.com/current-page -o shot.webpSee the ScreenshotNeo API documentation for request options. ScreenshotNeo accepts cookie or consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; those steps can be turned off. Bot checks, blank pages, timeouts, failed loads, and cache hits are not billed, and each response reports the page verdict and billing status in headers. Its MCP server gives AI agents screenshot, page-info, and PDF-capture tools. The free plan includes 1,000 screenshots per month with no card; paid plans start at $5 for 3,000 shots. Sign up for 1,000 free screenshots a month, with no card required.

Does changing og:image automatically update Facebook previews?
Not necessarily. The page must serve the new metadata, and the URL may need another scrape through the Sharing Debugger.
Should I enter the redirected destination or the original link in the Sharing Debugger?
Enter the exact URL people share so you can inspect its redirect and the metadata Facebook fetches.
