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) {
echo "PNG Support is enabled";
}
?&gt;
</programlisting>
