+/**
+* WOImage renders a dynamically generated IMG tag. The URL for the image SRC can be
+* static, or it can be generated dynamically to return a NSData object (with a mime-type)
+* or even return the contents of a file (not implemented yet).
+*
+* Bindings are:
+* <UL><LI>src: A static URL for the image source.</li>
+* <li>data: A NSData object with the image content. Must be used with mimeType.</li>
+* <li>mimeType: The MIME type for the image data. Can be used with filename or data bindings.</li>
+* <li>filename: The path to a file containing an image.</li>
+* <li>framework: The optional framework from whence the image should be retrieved (used in conjunction with filename).</li>
