+Demonstrates how to serve image data through a PageAction. You should see the Click
+logo rendered below:
+
+<p/>
+
+<img src="$context$path?pageAction=getStaticImageData" alt="Retrieve image data through a Page Action"/>
+
+<p/>
+
+A PageAction is processed
+by passing the parameter <span class="blue">pageAction</span> and a target
+Page method. In this example the Page method is <span class="red">getStaticImageData</span>.
+
+<p/>
+
+<pre class="codeHtml">
+<img src="$context$path?<span class="blue">pageAction</span>=<span class="red">getStaticImageData</span>"/></pre>
+
+<h3>Dynamic images</h3>
+
+You can easily load dynamic images by by passing request parameters.
+
+<p/>
+
+<img src="$context$path?pageAction=getDynamicImageData&imageName=home.png" alt="Retrieve dynamic image data through a Page Action"/>
+
+<p/>
+
+In this demo we pass to the server the name of the image to load. The parameter
+<span class="blue">imageName</span> controls which image to load, in this example
+<span class="red">home.png</span>.
+
+<p/>
+
+<pre class="codeHtml">
+<img src="$context$path?pageAction=getDynamicImageData&<span class="blue">imageName</span>=<span class="red">home.png</span>"/></pre>
