The files

The share picture: Alan Jay logo, Your next car is right down the road, and the road with cars

og.png 1200 by 630, 216 KB. Every app shows this.

og.mp4 1200 by 630, 3 seconds, 160 KB, no sound. iMessage plays this.

Blue icon: the A and J from the Alan Jay logo, white with a red edge, over the road

Pick Blue

White icon: the A and J exactly as in the logo, over the road

Option White

The A and J are the logo's own letters, cut from the header logo file, not redrawn. apple-touch-icon.png 180 by 180 is the icon iPhones save and iMessage shows small.

Tab icon at 32 pixels

What each app does

AppWhat it showsDoes it move?
iMessageThe big picture, the page title and the site name. Apple asks for pictures at least 900 wide and icons at least 108 square.Apple docsYes. Apple says it downloads an MP4 named in the page and plays it on its own, muted.Apple docs The server has to answer partial download requests, or iMessage falls back to the still.Developer tests
WhatsAppThe picture under 600 KB, the title in bold, about 80 letters of the description. Developers report pictures over about 300 KB getting dropped, so ours is 216 KB.Meta docsNo, still only.Tested by checkmyog
Facebook1200 by 630 is their recommended size. It saves the picture by its address, so a new picture needs a new file name.Meta docsNot promised. Their docs say video may not play inline.Meta docs
XA wide card at 2 to 1, so a thin strip may be cut from the top and bottom. Nothing important sits there.X docsNo. An animated GIF shows only its first frame.X docs
SlackThe picture and title from the same tags.Slack docsNo, video plays only for big services like YouTube.Older post
DiscordThe picture and title.Tested by checkmyogYes, with a play button.Tested by checkmyog

Green a source states it or someone tested it. Blue inferred from older or indirect sources.

Each page keeps its own og:title, og:description and og:url. Car pages can later swap og.png for the car's photo and drop the video lines.

Not tested yet

What I could not check

  • A real iMessage. I cannot send texts, so the bubbles above are drawings, not screenshots.
  • Whether iOS 26 plays the video. Apple's note says it does; nobody I found posted a test on a real phone.
  • The preview server. The local server here answers partial download requests with the whole file, which makes iMessage show the still. The alanjay.camberautomotive.com host needs to answer them properly.
  • WhatsApp, Facebook, Slack and X with the real link.

Two minute check once it is up

  • Text the link to yourself on your iPhone. The picture should move within a second or two.
  • If you texted the link before, add ?v=2 to the end. Phones remember old previews.
  • Send it to yourself on WhatsApp to see the still.

Your call

Blue or white icon

I picked blue: it reads at tab size and matches the blue bar at the top of the site. White is closest to the printed logo.

Words in the picture

Apple suggests no words in preview pictures because they show at many sizes. I kept the homepage line because it reads at about 15 point in a text bubble. The other choice is the logo and road alone.
