+	 This function returns a bit-field corresponding to the image formats
+	 supported by the version of GD linked into PHP.  The following bits
+	 are returned, IMG_GIF | IMG_JPG | IMG_PNG | IMG_WBMP.  To check for PNG
+	 support, for example, do this:
+     <example>
+      <title>ImageTypes</title>
+      <programlisting role="php">
+&lt;?php
+if(ImageTypes() &amp; IMG_PNG) {
