 When you install this extension, it deploys a Cloud Function that exposes an HTTP API. All requests must be sent to the /process endpoint of the function. You perform image operations by passing an operations query parameter—a URL-encoded JSON string defining the operations to execute.

+### Using Relative URLs (type: 'path')
+
+In addition to fetching images via remote URLs, this extension also supports relative paths through the type: 'path' input type. This is useful when you're serving images from your own domain (e.g. through a CDN, proxy, or local server during development).
+
+When you use type: 'path', the extension will prepend the hostname of the incoming request to the path to construct the full image URL.

+```ts
+const operations = [
+  {
+    operation: 'input',
+    type: 'path',
+    path: '/images/photo.jpg',
