+## Image support
+
+The `Img` tag only supports the following image locations. It specifically
+does not support image locations referring to bundled assets.
+
+* From the network: Use a URL prefixed by either `http://` or `https://`.
+
+* From local files on the device: Use an absolute path to the file, for example by
+ concatenating the file name with the path returned by a known storage location,
+ such as those provided by the [`path_provider`](https://pub.dartlang.org/packages/path_provider)
+ plugin.
