I am developing a php web site. Here I need to create thumbnail of jpg, png and gif images

See my current code

if (@$fileType=="image/gif")
{
$im=ImageCreateFromGIF($add);
$width=ImageSx($im);              // Original picture width is stored
$height=ImageSy($im);                  // Original picture height is stored
$newimage=imagecreatetruecolor($n_width,$n_height);
imageCopyResized($newimage,$im,0,0,0,0,$n_width,$n_height,$width,$height);
if (function_exists("imagegif")) {
Header("Content-type: image/gif");
ImageGIF($newimage,$tsrc);
}
elseif (function_exists("imagejpeg")) {
Header("Content-type: image/jpeg");
ImageJPEG($newimage,$tsrc);
}
chmod("$tsrc",0777);
}////////// end of gif file thumb nail creation//////////


////////////// starting of JPG thumb nail creation//////////
if($fileType=="image/jpeg" or $fileType=="image/jpg"){
$im=ImageCreateFromJPEG($add); 
$width=ImageSx($im);              // Original picture width is stored
$height=ImageSy($im);             // Original picture height is stored
$newimage=imagecreatetruecolor($n_width,$n_height);                 
imageCopyResized($newimage,$im,0,0,0,0,$n_width,$n_height,$width,$height);
ImageJpeg($newimage,$tsrc);
chmod("$tsrc",0777);
}

Here I need to create thumbnail of png images. But I don't know how?

I sit possible to add thumbnail creation of png image within the existing code?

You can do the same thing as in JPEG thumbnail creation part but change JPEG to PNG instead.

if($fileType=="image/png"){
   $im=ImageCreateFromPNG($add); 
   $width=ImageSx($im);              // Original picture width is stored
   $height=ImageSy($im);             // Original picture height is stored
   $newimage=imagecreatetruecolor($n_width,$n_height);                 
   imageCopyResized($newimage,$im,0,0,0,0,$n_width,$n_height,$width,$height);
   ImagePng($newimage,$tsrc);
   chmod("$tsrc",0777);
}

Also, please look at the PHP manual http://www.php.net/manual/en/ref.image.php for any other formats.
