+Random Image plugin for LifeType
+Author: Jon Daley
+Contact URL: http://limedaley.com/
+
+Example URL using this plugin: http://groshlink.net/ 
+  (click into any of the categories to see the images on the right)
+
+
+Example template code:
+
+{if $randomimage}
+  <li>
+    <a title="Eden (2006)" href="http://groshlink.net/album/eden_06">
+      <img src="{$randomimage->getImage("eden_06", "PREVIEW")}" border="0" />
+    </a>
+  </li>
+  <li>
+    <a title="Graduate & Faculty Ministry" href="http://groshlink.net/album/graduate__faculty_ministry">
+      <img src="{$randomimage->getImage("graduate__faculty_ministry", "PREVIEW")}" border="0" />
+    </a>
+  </li>
+  <li>
+    <a title="Pittsburgh" href="http://groshlink.net/album/pittsburgh">
+      <img src="{$randomimage->getImage("pittsburgh", "PREVIEW")}" border="0" />
+    </a>
+  </li>
+{/if}
+
+
+
+TODO:
+  Have the album links, and <a title> strings generated automatically
+   probably with a parameter or configuration options so it works for
+   everyone
+
+  Probably can get rid of the SQL query in the plugin and use class
+   methods for better compatibility
