To change a Facebook link preview image, change the Open Graph/share image on the webpage you are linking to, publish that page, then submit the complete URL to Facebook Sharing Debugger and select Scrape Again. Facebook normally reads the image from the linked page; the ordinary post composer is not a reliable place to replace it. A fresh scrape updates the information Facebook can retrieve, but it does not guarantee that a card already attached to a published post will change.

What controls the image in a Facebook link preview?

The preview card is built from metadata available on the linked webpage. The publisher-side control is the page’s social-sharing or Open Graph image. Changing a photo inside Facebook after pasting a URL is not the documented solution for an ordinary organic Page post.

Meta announced in July 2017 that Pages other than media publishers would no longer be able to override link metadata such as the headline, description, or image through the API or Page publisher. Meta described Open Graph markup and Sharing Debugger as the way to prepare and preview link attachments. A practitioner guide updated in February 2025 reports the same restriction for organic Page link previews. The exact eligibility of media-publisher exceptions can change, so check current Meta documentation if that distinction affects your Page.

Before you start

  • Control of the source page: You need access to the website or CMS that owns the URL. If you do not control it, ask its owner to change the share image.
  • The exact public URL: Facebook scrapes the URL you submit. A different protocol, subdomain, path, query string, or redirect can represent a different page.
  • A published change: Saving an image in a private draft or media library is not enough. The page must be published so Facebook can retrieve the new metadata.

Change the image step by step

1. Open the page-level sharing settings

In your website builder or CMS, edit the specific page that people will share. Look for a setting named Share image, Social image, Open Graph image, or similar. Labels and locations differ by platform; do not assume that the site’s general logo or default social image is the page’s current value.

Meta Portal - Smart Video Calling for the Home with 10” Touch Screen Display - Black
  • A more natural connection. Smart Camera adjusts automatically so you can move freely and stay in frame, while Smart Sound ensures you can easily be heard.
  • Call anyone, anywhere. Use apps like Messenger and WhatsApp to connect with friends and family—even if they don’t have a Meta Portal.
  • Designed for the home. With a sleek picture frame design, quick setup and intuitive voice and touchscreen controls, Portal fits easily and seamlessly into your home.
  • Privacy by design. Easily disable the camera and microphone, or block the lens with the camera cover.

2. Choose the new share image

Select or upload the image intended for Facebook’s link card, and save the page’s social metadata. If the page has its own image field, use that rather than changing only a site-wide default. A page-specific value should take precedence for that URL when the platform publishes it correctly.

3. Publish the webpage

Publish or update the page, then open the public URL in a normal browser window. Confirm that you are viewing the live page, not a preview address or an administrator-only version. If your CMS uses separate save and publish actions, complete both.

4. Request a new scrape

  1. Open Facebook Sharing Debugger.
  2. Enter the complete public URL, including the correct https:// scheme and path.
  3. Inspect the Link Preview or detected information shown by the tool.
  4. Select Scrape Again to ask Facebook to retrieve the current page metadata.

Showit’s current help guidance includes publishing the page and scraping again; PhotoBiz likewise instructs users to enter the full URL and inspect the Link Preview section. If the debugger still displays the old image, verify the saved page setting and published status, then submit the exact URL again and select Scrape Again.

5. Create or edit the Facebook post

For a new post, paste the URL after the debugger shows the intended image, wait for Facebook to build the card, and then add your text before publishing. Do not remove the URL until Facebook has generated the attachment if you want the link card to remain associated with the post.

New posts and existing posts behave differently

Situation What you can reasonably expect
New post created after the page is updated and scraped Facebook can use the newly retrieved metadata when it builds the card.
Already-published post A new scrape refreshes information Facebook can retrieve, but available support guidance does not guarantee that the card already attached to that post will change.
URL you do not control You cannot perform the source-side fix. Ask the website owner to update its page image and publish the change.

If an old post is important and still shows the wrong image, the dependable practical option is usually to create a new post after the source page and scrape have been updated. Do not promise a retroactive repair merely because Sharing Debugger accepts the URL.

If you do not own the linked website

Facebook’s composer cannot give you reliable control over another site’s metadata. Send the site owner the exact URL and explain that its page-level social-sharing/Open Graph image needs to be changed and published. The owner can then request a fresh scrape. You can choose a different URL that you do control, but changing text or adding a different photo to your Facebook post does not replace the link card’s source image.

Troubleshooting an old or missing image

The debugger still shows the previous image

  • Reopen the page in your CMS and confirm the new image is assigned to that specific page, not only selected in a draft or global default.
  • Publish the page again and verify the public URL.
  • In Sharing Debugger, submit the complete URL and select Scrape Again.
  • Check that you did not submit a different URL variant, such as a www versus non-www hostname, a redirected address, or a URL with a different path.

The Facebook post still has the old card

That post may already contain an attachment created before the source metadata was refreshed. The available guidance warns that a successful re-scrape does not guarantee a change to an existing published post. Test by creating a new post after the debugger displays the new information.

You changed the site logo but not the preview

A site-wide logo, browser favicon, or article thumbnail is not necessarily the page’s social-sharing image. Return to the page-level setting and update the field used for Facebook/Open Graph sharing.

  • Move and talk freely with Smart Camera: With Smart Camera, you don’t have to worry about being out of frame.

And as more people enter a room, Smart Camera automatically widens to keep everyone in view, so you don’t miss a moment

You can also completely disable the camera and microphone with a single tap, or block the camera lens with the camera cover provided
  • Connect with friends, even if they don't have Portal: Easily call friends and family on Messenger — calls can be made seamlessly to and from smartphones and tablets. And you can bring up to six other people into a group call
  • Alexa built-in: Portal has Alexa built-in, so you can ask a question, set a timer, add items to your shopping list, control your smart home or more. Just ask
  • Experience more together: With Portal, story time will never be the same. With music, animation and augmented reality effects, Portal lets you become some of your children’s favorite characters as you read along to well-loved stories. And if friends or family also have Portal, you can listen to your favorite music together as if you were in the same room, without delays or feedback

You cannot find a share-image setting

Platform terminology varies. Search your CMS documentation for “Open Graph,” “social sharing,” or “social image,” or ask the site administrator where page-level sharing metadata is managed. If the platform exposes no such control, its owner or developer may need to add the metadata to the page template.

The preview appears for one URL but not another

Facebook processes the URL it receives, not the page you intended in general. Compare the full strings character by character, including protocol, hostname, path, and query parameters. A redirect can also lead to a different final page.

What not to rely on

  • A composer-only image replacement: For ordinary organic Page posts, do not treat a temporary composer control or an image attached to your text as a guaranteed replacement for the link card image.
  • Changing only the Facebook caption: Caption text does not alter the metadata Facebook reads from the linked page.
  • Assuming a scrape rewrites history: Refreshing retrieved metadata is not the same as editing every attachment already published.
  • Guessing at exceptions: Meta’s 2017 policy distinguished media publishers from other Pages, but the sources available here do not establish current eligibility rules. Confirm current Meta documentation if you operate a media Page or use a special publishing integration.

A repeatable publishing checklist

  1. Confirm that you control the source webpage.
  2. Set the page’s social-sharing/Open Graph image.
  3. Save and publish the page.
  4. Open the live URL to confirm it is publicly reachable.
  5. Submit that exact URL to Sharing Debugger.
  6. Inspect the detected preview and select Scrape Again when needed.
  7. For a reliable test, create a new Facebook post after the new preview appears in the debugger.

Or skip the browser setup

If your goal is to verify what the updated webpage looks like before sharing it, ScreenshotNeo can capture the public source page by API. It does not change Facebook’s metadata or force an existing Facebook card to update; it gives you a clean image of the page you control.

One GET request returns a PNG, JPEG, WebP, or PDF. The API can accept the URL, wait for a selector or network idle, run custom JavaScript, and capture a full page or a selected element. See the ScreenshotNeo API documentation for parameters.

FAQ

Can I change the image after I paste the link into Facebook?

For an ordinary organic Page post, use the source webpage’s share image and Sharing Debugger instead of relying on a composer-level replacement.

How long should I wait after publishing the new image?

The documented workflow is to publish the page and request a fresh scrape; it does not specify a universal waiting period. Check the debugger’s detected preview rather than relying on elapsed time alone.

Will changing the image update every place the URL was shared?

No guarantee is established for already-published attachments. Treat a new post as the reliable test after the debugger shows the updated metadata.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Can ScreenshotNeo change my Facebook preview?

No. It can capture and inspect the public webpage that supplies the metadata, but only the page owner and Facebook’s scraping process determine the link card.
