# Generate Twitter link preview images for every page

Use one HCTI og:image pattern across your site. Each page supplies its own metadata, and HCTI keeps the matching Twitter image current without a separate image-generation request.

## Key capabilities

- 1200 × 600 images for tweets
- Updates when preview inputs change
- No extra code per page

## When to use this feature

Use HCTI Dynamic Open Graph Images when a site has many public pages that need current, page-specific link preview images. Configure one URL pattern instead of calling an image-generation API from every publishing workflow. Each page can provide screenshot options or template values through meta tags, and unchanged inputs reuse the existing image. The source pages must be reachable by HCTI; use the [URL Screenshots feature](https://htmlcsstoimage.com/features/url-screenshots.md) for ordinary webpage captures that are not driven by link-preview metadata, or [Signed Image URLs](https://htmlcsstoimage.com/features/signed-image-urls.md) when the complete render request belongs in the image URL itself.

## Add one Twitter Card image URL pattern

Set `twitter:image` to an HCTI URL containing the current page path. HCTI opens that page, reads its supported meta tags, and returns the matching cached image.

```html
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:image" content="https://hcti.io/v1/og/YOUR_DOMAIN_ID/articles/product-launch">
<meta property="hcti:selector" content="#social-card">
```

## Choose how each image is made

- **Page screenshot:** Add `hcti:` meta tags to select an element, apply page-only CSS, set timing, or provide other eligible screenshot options.
- **Reusable template:** Add `html:tv:` meta tags to populate variables in a maintained HCTI template.
- **Content-aware reuse:** If the resolved screenshot or template inputs have not changed, HCTI returns the existing image.
- **Controlled metadata refresh:** The configuration controls when HCTI checks a page again, and origin cache headers or ETags can postpone or simplify that check.

## Twitter preview size

Twitter previews use a 1200 × 600 target. Choose one shared image, fit a single render to recognized preview sizes without squashing it, or render each size with its own viewport.

## Test and configure

Use the [social card previewer](https://htmlcsstoimage.com/tools/social-card-previewer/twitter) to inspect a public page's current image, title, description, fallbacks, and platform-shaped preview.

Create and manage dynamic Open Graph configurations in the [HCTI dashboard](https://htmlcsstoimage.com/dashboard/og-configs). See the [setup guide](https://docs.htmlcsstoimage.com/getting-started/og-images/) and [supported metadata parameters](https://docs.htmlcsstoimage.com/getting-started/og-images/supported-parameters/) for implementation details.
