How to Make a Bengali Blog Post Show Its Image in Facebook Link Previews

To make a Bengali blog post show its image in a Facebook link preview, set an explicit og:image URL for that individual post, publish the change, then inspect the exact post URL in Facebook’s Sharing Debugger and request a fresh scrape if it shows old data. The page’s HTML head should also include og:title, og:type and og:url. Bengali text does not require different image markup.

The key check is the metadata Facebook can read from the published page. A featured image may appear on the article itself without being emitted as the page’s Open Graph image.

1. Choose the image for this specific post

Pick the image you want people to see when they share this article. The page’s visible featured image and its social sharing image are separate settings in some themes and publishing workflows. Confirm that the rendered page’s og:image points to your intended image file.

Use an image URL that is publicly fetchable. The Open Graph protocol identifies og:image as the image representing the page. It also defines optional image properties such as dimensions, MIME type, secure URL and alt text. Its example dimensions are illustrative; they are not a universal Facebook image-size recommendation.

Open the Bengali post in the WordPress editor.
Look for the SEO plugin’s or theme’s social or Facebook sharing panel.
Set the social image for this post. Do not assume that setting the ordinary featured image also sets og:image.
Save or update the post, then open the public article URL.

Check the plugin or theme documentation if the editor does not show a social-image field. WordPress support examples describe custom images in an SEO plugin’s Social tab, but the available controls depend on the site’s setup. If there is no suitable per-post control, add the metadata in the theme or template.

3. Add Open Graph tags in the page template if needed

The Open Graph protocol lists og:title, og:type, og:image and og:url as the four required properties for a page. Use one source for these tags: a plugin, theme or custom template. Two sources can emit conflicting duplicate values.

<head>
  <meta property="og:title" content="Your Bengali article title">
  <meta property="og:type" content="article">
  <meta property="og:url" content="https://example.com/bengali-article/">
  <meta property="og:image" content="https://example.com/images/bengali-article.jpg">
  <meta property="og:description" content="A short description of the article.">
  <meta property="og:image:alt" content="Description of the article image">
</head>

Replace the example URLs and text with the canonical article URL, the selected image URL, and metadata appropriate to the post. Keep the title and description in the post’s intended language. Make sure the tags are present in the published document head and do not depend on client-side JavaScript to add them after page load.

Protocol reference: The Open Graph protocol.

4. Inspect the exact article URL in Facebook

Publish the metadata change.
Open Facebook’s Sharing Debugger and enter the full URL of the individual Bengali article, not the site homepage.
Inspect the metadata Facebook reports and confirm that og:image points to the intended file.
If the debugger shows old preview data, request a fresh scrape, then inspect the result again.
Make a new test share after the debugger reads the updated metadata.

A fresh scrape is a cache-refresh and diagnostic step. It does not promise that every existing Facebook post will be rewritten with the new image.

5. Troubleshoot a missing preview image

Symptom	Likely cause	What to check or change
The debugger reports no image	The page does not emit `og:image`.	Inspect the published HTML head. Set a social image for the post or add the tag in the template.
The wrong image appears	The tag points to another image, or multiple plugins or theme code emit competing values.	Find every `og:image` in the rendered HTML. Keep one intended source and remove or correct duplicates.
The page shows the right image, but the preview does not	The visible featured image may not be the Open Graph image.	Check the actual `og:image` URL in the published source and set the per-post social image explicitly.
Facebook cannot read the page	A server, firewall, CDN or cache response may block the fetch. A WordPress support example reports a `403` page response.	Check the debugger’s reported response and your server, security, CDN and cache settings. Confirm that the public article can be fetched.
The image URL is correct, but the image is unavailable	The image file may not be publicly fetchable or may return an error.	Open the exact image URL without a logged-in session and check the server/CDN response. Use an accessible image URL.
The old image remains after editing	Facebook may still have cached the earlier metadata.	Request a fresh scrape for the exact article URL, verify the new metadata, and test with a new share.
The social image field is missing in WordPress	The active theme or SEO plugin may not expose a per-post social control.	Check its settings and documentation, or have the template emit the Open Graph tags.

Diagnose in this order: confirm the published page emits the right tag; confirm the image URL is reachable; check whether the page or image fetch is blocked; then refresh Facebook’s scrape. Changing image dimensions or installing another plugin will not fix missing metadata or a blocked fetch by itself.

6. Choose a maintainable implementation

Approach	Best fit	Check before relying on it
SEO plugin or theme social-image field	Editors need to choose an image separately for each post.	Verify it emits the chosen URL as `og:image` in the published head.
Theme or template metadata	The site needs a controlled implementation or has no editor field.	Ensure values are correct per post, only one source emits tags, and crawlers can read the HTML without client-only rendering.

Either route works when the resulting HTML has the correct metadata for that article. The WordPress support forum has examples of missing image metadata, plugin social-image controls and a reported 403 response; those examples illustrate possible problems and are not guarantees about every site. See WordPress.org Support.

Or skip the browser setup

If you need to inspect how an article URL responds or capture a page for review, ScreenshotNeo is a website screenshot API and MCP server. A screenshot can help you review the rendered page, but it does not replace checking the page’s Open Graph metadata or the Facebook Sharing Debugger.

One GET request returns an image or PDF. See the ScreenshotNeo API documentation.

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.com/bengali-article/ -o shot.webp

import requests

r = requests.get(
    "https://api.screenshotneo.com/v1/shot",
    params={"access_key": "YOUR_API_KEY", "url": "https://example.com/bengali-article/"},
    timeout=90,
)
open("shot.webp", "wb").write(r.content)

const q = new URLSearchParams({
  access_key: 'YOUR_API_KEY',
  url: 'https://example.com/bengali-article/'
});
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);
if (!res.ok) throw new Error(`Screenshot request failed: ${res.status}`);
const fs = await import('node:fs/promises');
await fs.writeFile('shot.webp', Buffer.from(await res.arrayBuffer()));

ScreenshotNeo removes cookie banners, newsletter popups and chat widgets before capture; bot checks, blank pages and failed loads are never billed. Its MCP server lets AI agents take screenshots. The free plan includes 1,000 screenshots a month with no card, and paid plans start at $5 for 3,000 screenshots.

Performance and reliability notes

Keep the social image URL stable and publicly accessible so the metadata continues to point to a fetchable file.
When changing an image, verify the new URL in the published HTML and then refresh the debugger’s scrape.
A successful browser view does not prove Facebook can fetch the page or image; inspect the crawler-facing response when the debugger reports an error.
There is no need to add a new plugin solely to change image dimensions before confirming which image URL the page emits.

FAQ

Does Bengali text need special Open Graph tags?

No. Use the same Open Graph properties. Write the title and description in the language appropriate to the post.

Why does the featured image appear on my site but not in Facebook?

The site may display its featured image without using it for og:image. Check the published head and set the social image explicitly.

Should I use the homepage URL in the debugger?

No. Inspect the full URL of the exact post whose preview you want to fix.

Will a fresh scrape update shares already posted?

It refreshes the information Facebook reads for a URL; it does not guarantee every existing post will be rewritten.
