A private home's shared link now previews as its own blurred photo
Your answer, built.
“Can we do like a combo — like not just the standard social share card, but if you like a green blurred photo that says login to see listing?”
What someone in the group chat now sees
Same card, at the sizes iMessage, WhatsApp, Slack, X, Facebook and LinkedIn actually draw it.
Where the green comes from
Top: the host's real photo. Middle: the only thing the card is ever built from — 20 × 11 pixels, 790 bytes, 220 colour samples. Bottom: the card.
Four different homes, four different cards
Every one takes its colour and mood from its own photo. Not one of them shows a house.
Why the real photo can't be got back
The card isn't a blurred copy of the photo. It's a different, much smaller picture, made from 220 average colours — and the house was thrown away before the card was drawn, on the photo server, not in the browser.
- There is no filter to switch off. A blur laid over a real photo would leave the real photo sitting there. This one has nothing underneath it.
- The card's web address takes no settings. Asking it for a bigger, sharper or unblurred version — 19 different ways were tried — returns the exact same file, byte for byte.
- Nothing anyone receives names the original. Not the card, not its headers, not the listing page. The photo is fetched privately by our server and never mentioned again.
- Nothing is hidden inside the file. No location, no GPS, no camera details, no secret thumbnail — checked, and checked again on the live site.
- It is measured, not assumed: an automatic check reads the finished picture a chat app was actually served and scores how much detail is left. A real photo scores about 327. Our cards score 0.08 – 0.31. Anything over 5 blocks the release.
Public listings didn't change
A public home still previews with its own full photo, exactly as before.
The homes shown here are a demo listing made for this work — a stock photograph, not a member's home. Nothing on this page is anyone's real address or private home.
