Replaces the author avatar in the discussion list with the first image found in the discussion's opening post. How it works ------------ [](#how-it-works) When the discussion list is rendered, each discussion's author avatar is replaced with a thumbnail of the first `` found in the HTML of the first post. If the first post contains no image, the normal user avatar is shown instead. **Backend:** `AddDiscussionThumbnail` is registered as an API serializer attribute on `BasicDiscussionSerializer`. For each discussion it: 1. Loads the first post and calls `formatContent()` to render the full HTML 2. Extracts the `src` of the first `` tag via regex 3. Caches the result forever against the post ID, keyed as `fof:discussion-thumbnail:discussion:{id}` 4. Returns the URL as the `customThumbnail` attribute on the discussion The cache is invalidated when the post's `edited_at` timestamp is newer than the cached date, so editing the first post to change its image is reflected on next load. **Frontend:** The `customThumbnail` attribute is read in a `contentItems` extension on `DiscussionListItem`. When a thumbnail URL is present, the `authorAvatar` item is replaced with a `DiscussionThumbnail` component wrapped in the same `Tooltip` + `Link` structure as the normal avatar. The thumbnail is styled with the `.Avatar` class so it matches core avatar sizing and alignment at all breakpoints. Settings -------- [](#settings) SettingDefaultDescriptionLink to discussion`false`When enabled, clicking the thumbnail navigates to the discussion instead of the author's profileInstallation ------------ [](#installation) ``` composer require fof/discussion-thumbnail:"*" ``` Enable the extension in your Flarum admin panel.
