+    !!! tip "Hosting images externally and optimizing them automatically"
+
+        This option makes the [built-in privacy plugin] an excellent choice for
+        when you want to host assets like images outside of your git repository
+        in another location to keep them fresh and your repository lean.
+
+        Additionally, as of [:octicons-tag-24: insiders-4.30.0][Insiders], the
+        built-in privacy plugin was entirely rewritten and now works perfectly
+        with the [built-in optimize plugin], which means that external assets
+        can be passed through the same optimization pipeline as the rest of your
+        documentation. This means you can store and edit unoptimized files
+        outside of your repository, and let both plugins built a highly
+        optimized site for you.
+
+        If you want to implement separate pipelines, i.e., optimize some images
+        differently from others or exclude some images from downloading, you can
+        use multiple instances of the [built-in privacy plugin].
