In PHP4 as of version 4.0.2 you can use the function
<function>imagetypes</function> in place of
<function>function_exists</function> for checking
the presence of the various supported image formats:
<informalexample>
<programlisting role="php">
if (ImageTypes() &amp; IMG_GIF) {
Header("Content-type: image/gif");
ImageGif($im);
}
elseif (ImageTypes() &amp; IMG_JPG) {
... etc.</programlisting>
