 More control over the ``img`` tag
 ---------------------------------
 
-In some cases greater control over the ``img`` tag is required, for example to add a custom ``class``. Rather than generating the ``img`` element for you, Wagtail can assign the relevant data to another object using Django's ``as`` syntax:
+Wagtail provides two shorcuts to give greater control over the ``img`` element:
+
+.. versionadded:: 0.4
+**Adding attributes to the  {% image %} tag**
+
+Extra attributes can be specified with the syntax ``attribute="value"``:
+
+.. code-block:: django
+
+    {% image self.photo width-400 class="foo" id="bar" %}
+
+No validation is performed on attributes add in this way by the developer. It's possible to add `src`, `width`, `height` and `alt` of your own that might conflict with those generated by the tag itself.

+Wagtail can assign the image data to another object using Django's ``as`` syntax:
 
 .. code-block:: django
     
-    {% load image %}
-    ...
     {% image self.photo width-400 as tmp_photo %}
 
     <img src="{{ tmp_photo.src }}" width="{{ tmp_photo.width }}" 
         height="{{ tmp_photo.height }}" alt="{{ tmp_photo.alt }}" class="my-custom-class" />
 
+.. versionadded:: 0.4
+The ``attrs`` shortcut
+-----------------------
+
 You can also use the ``attrs`` property as a shorthand to output the ``src``, ``width``, ``height`` and ``alt`` attributes in one go:
 
 .. code-block:: django
 
     <img {{ tmp_photo.attrs }} class="my-custom-class" />
