 - Plugin SDK: re-export `isPrivateIpAddress` from `plugin-sdk/ssrf-runtime`, restoring source-checkout builds for SearXNG and Firecrawl private-network guards. Thanks @vincentkoc.
 - CLI/directory: report unsupported directory operations for installed channel plugins instead of prompting to reinstall the plugin when it lacks a directory adapter. Fixes #75770. Thanks @lawong888.
 - Web search/SearXNG: show the JSON API `search.formats` prerequisite during SearXNG setup before prompting for the base URL. Supersedes #65592. Thanks @evanpaul14.
+- Web search/SearXNG: pass through `img_src` image URLs from SearXNG image-category results. Supersedes #61416. Thanks @sghael.
 - Web search: keep public provider requests on the strict SSRF guard and reserve private-network access for explicit self-hosted SearXNG/Firecrawl endpoints. Fixes #74357 and supersedes #74360. Thanks @fede-kamel.
 - Web search/Firecrawl: allow self-hosted private/internal Firecrawl `baseUrl` endpoints, including HTTP for private targets, while keeping hosted Firecrawl on the strict official endpoint. Fixes #63877 and supersedes #59666, #63941, and #74013. Thanks @jhthompson12, @jzakirov, @Mlightsnow, and @shad0wca7.
 - Providers/OpenRouter: strip trailing assistant prefill turns from verified OpenRouter Anthropic model requests when reasoning is enabled, so Claude 4.6 routes no longer fail with Anthropic's prefill rejection through the OpenAI-compatible adapter. Fixes #75395. Thanks @sbmilburn.

 ## Notes
 
 - **JSON API** -- uses SearXNG's native `format=json` endpoint, not HTML scraping
+- **Image result URLs** -- image-category results include `img_src` when SearXNG
+  returns a direct image URL
 - **No API key** -- works with any SearXNG instance out of the box
 - **Base URL validation** -- `baseUrl` must be a valid `http://` or `https://`
   URL; public hosts must use `https://`
