Upload and thumbnail creation (png & bmp)

[argrafic]

Hello all,

 

I'm using the script from this site: http://www.theopensurgery.com/29/php-upload-and-resize-image-script/#comment-415

 

I have it working for jpg and gif, but can't get it to work with png and bmp.

 

Help!! Please!!! Thanks!!!

 

Here's the part of the code that makes the thumbnails:

if (isset ($_FILES['gi_imagen'])){
	$imagename = $_FILES['gi_imagen']['name'][$i];
	$source = $_FILES['gi_imagen']['tmp_name'][$i];
	$tipo = $_FILES['gi_imagen']['type'][$i];
	echo "<br>Tip: ".$tipo;

	$target = "../galerias/".$gal."_".$imagename;
	move_uploaded_file($source, $target);
	$imagepath = $gal."_".$imagename;
	$save = "../galerias/".$gal."_"."tn_".$imagename; //thumbnail
	$file = "../galerias/".$imagepath; //original
	list($width, $height) = getimagesize($file);
	$modwidth = 80;
	$diff = $width / $modwidth;
	$modheight = $height / $diff;
	$tn = imagecreatetruecolor($modwidth, $modheight);

	if($tipo == "image/pjpeg" || $tipo == "image/jpeg" || $tipo == "image/jpeg" || $tipo == "image/JPG" || $tipo == "image/jpg"){
		$image = imagecreatefromjpeg($file);
	} else if($tipo == "image/gif" || $tipo == "image/GIF"){
		$image = imagecreatefromgif($file);
	} else if($tipo == "image/bmp" || $tipo == "image/BMP"){
		$image = imagecreatefromwbmp($file);
	} else if($tipo == "image/X-PNG" || $tipo == "image/PNG" || $tipo == "image/png" || $tipo == "image/x-png"){
		$image = imagecreatefrompng($file);
	}	

	imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height);

	if($tipo == "image/pjpeg" || $tipo == "image/jpeg" || $tipo == "image/jpeg" || $tipo == "image/JPG"){
		imagejpeg($tn, $save, 100);
	} else if($tipo == "image/gif" || $tipo == "image/GIF"){
		imagegif($tn, $save, 100);
	} else if($tipo == "image/bmp" || $tipo == "image/BMP"){
		imagewbmp($tn, $save, 100);
	} else if($tipo == "image/X-PNG" || $tipo == "image/PNG" || $tipo == "image/png" || $tipo == "image/x-png"){
		imagepng($tn, $save, 100);
	}

	echo "<br>Img: ".$img = $imagepath; //imagen final
	echo "<br>Thmb: ".$thb = $gal."_"."tn_".$imagename; //thumbnail final
}
