og:image bookmarklet

Show the picture you saw in the feed

What it does

Articles declare a “share image” (og:image, twitter:image, JSON-LD image) that Google Discover, Facebook, X, LinkedIn… show in their cards. Many sites never display that picture in the article itself — you tap an interesting photo and it’s gone.

Run this bookmarklet on the article: it overlays every declared share image, full size, with its dimensions, an Open image link and a Copy URL button. It also re-reads the page as the server sent it, in case scripts removed the tags. Tap it again, tap outside or press Esc to close. Nothing leaves your browser.

🖼 og:image

Install on desktop (Chrome, Edge, Firefox, Safari)

Show the bookmarks bar (Ctrl/⌘ + Shift + B).
Drag the 🖼 og:image button above onto the bookmarks bar.
On any article, click the bookmark.

Chrome on Android / iOS — the easy way: sync from desktop

Mobile Chrome can’t drag links into bookmarks and makes editing a bookmark’s URL tedious. Let sync do it.

On desktop Chrome, be signed in to the same Google profile as on your phone, with sync on and Bookmarks included (chrome://settings/syncSetup → Manage what you sync).
Install it on desktop as above (drag to the bookmarks bar). Keep the name short and unique — rename it to e.g. ogimg (right-click → Edit) so it’s easy to summon on the phone.
Wait a minute: it appears on the phone under Bookmarks → Bookmarks bar.
To run it on mobile: on the article, tap the address bar, type ogimg, and tap the bookmark suggestion (the one with the star / bookmark icon) in the dropdown.
Opening it from the Bookmarks screen does not work — Chrome only runs javascript: bookmarks launched from the address bar.

Install directly on the phone (no desktop)

Tap Copy bookmarklet code above.
Bookmark this page (⋮ → ☆).
Open Bookmarks, long-press the new bookmark → Edit. Set the name to ogimg and replace the URL with the copied code (it starts with javascript:). Save.
Run it from the address bar, as above. On iOS Safari, run it from the Bookmarks list directly.

If copying doesn’t work, select all the code here:

Coming from Google Discover or a social app?

Discover, Google News and most social apps open links in an in-app browser (Custom Tab / web view) where bookmarks don’t exist. Use ⋮ → Open in Chrome first, then run the bookmarklet.
If the article is an AMP page (google.com/amp/…), open the original site link first — the AMP viewer frame hides the article’s tags.
If an image is listed but can’t be displayed in the overlay (some sites block it), Open image in a new tab usually works.

Source: og-image.js — the bookmark is that function, lightly minified.
