 * <b>3.1.4 PHOTO Type Definition</b>
 * <ul>
 * 	<li><b>Type name:</b> PHOTO</li>
 * 	<li><b>Type purpose:</b> To specify an image or photograph information that annotates some aspect of the object the vCard represents.</li>
 * 	<li><b>Type encoding:</b> The encoding MUST be reset to "b" using the ENCODING parameter in order to specify inline, encoded binary data. If the value is referenced by a URI value, then the default encoding of 8bit is used and no explicit ENCODING parameter is needed.</li>
 * 	<li><b>Type value:</b> A single value. The default is binary value. It can also be reset to uri value. The uri value can be used to specify a value outside of this MIME entity.</li>
 * 	<li><b>Type special note:</b> The type can include the type parameter "TYPE" to specify the graphic image format type. The TYPE parameter values MUST be one of the IANA registered image formats or a non-standard image format.</li>
 * </ul>
