## What iMessage needs

- Messages uses `og:title` and `og:image` (or `og:video`); without an image it shows the site icon (`apple-touch-icon`) next to the title.
- Apple advises images at least 900 px wide and files no larger than 10 MB.
- Apple advises against text in the preview image: Messages shows it at different sizes on different devices.
- The preview is fetched on the sender's device when the link is pasted.

## iMessage link preview not showing or not updating?

- No big image? Check og:image is absolute, at least 900 px wide and under 10 MB.
- Small icon only? That is the no-image layout — add og:image, and an apple-touch-icon for the icon.
- Messages documents no refresh; a changed page shows the new preview when the link is pasted again in a new message.

## Questions

### What image size does iMessage use for link previews?

Apple's technote asks for images at least 900 px wide and no larger than 10 MB. 1200×630 works.

### Why does iMessage show a small icon instead of an image?

The page has no og:image Messages can use, so it falls back to the site icon. Add og:image (and an apple-touch-icon for the icon itself).

### Should I put text in the image?

Apple advises against it: the image is shown at different sizes on iPhone, iPad and Mac. Large, short headlines survive; small text does not.
