imagecreatetruecolor problem

[Harley1979]

I am using imagecreatetruecolor within a script for resizing my images which is causing me a problem.

 

For some reason instead of creating a black to my dimensions image like it should do, I am getting "resource id#6" as its value which of course is an invalid image resource.

 

Has anyone else ever experienced this before, what is it and why can I not simply create a blank image?

 

I have a hunch it is something to do with the php/gd setup which to me looks fine.

 

P.S. I am using GD2.

 

Thanks

If you'd care to post some code using the [code] and [/code] brackets that would help...

Here you go:

 

	$path = "../gallery/";
$thumbPath = "../gallery/thumbs/";

$max_size = 3000000;

$original = $_FILES['imagefile']['tmp_name'];
$size = $_FILES['imagefile']['size'];
$type = $_FILES['imagefile']['type'];

if(isset($original)){
	$imageMsg = "You must choose an image to upload";
}

if(is_uploaded_file($original)){

	if($size > $max_size){
		$imageMsg = "The image is just too feckin big!";
		$err = true;
	}

	if($type == "image/jpeg" || $type == "image/gif"){

	// get last image from db
	$result = mysql_query("SELECT photo FROM gallery ORDER BY id desc LIMIT 1");
	$row = mysql_fetch_row($result);

	// create image name
	if(empty($row[0])){$photoName = 0;}
	$photoName = $row[0] + 1;
	$newName = $photoName.".jpg";

	// begin create thumbnail				
	list($width, $height) = getimagesize($original);

	// set crop size
	if($width > $height){
		$biggestside = $width;
	} else {
		$biggestside = $height;
	}

	// crop size will be half that of the largest side
	$croppercent = .15;
	$cropwidth = $biggestside*$croppercent;
	$cropheight = $biggestside*$croppercent;

	// get top left coordinate
	$cl = array("x"=>($width-$cropwidth)/2, "y"=>($height-$cropheight)/2);

	// create thumbnail
	$thumbsize = 75;
	$thumb = imagecreatetruecolor($thumbsize, $thumbsize);
	imagecopyresampled($thumb, $original, 0, 0, $cl['x'], $cl['y'], $thumbsize, $thumbsize, $cropwidth, $cropheight);

	// save to path
	imagejpeg($thumb, $thumbPath.$newName);

	list($origWidth, $origHeight) = getimagesize($original);

	// if our image is not the desired dimension, resample to default dimensions		
	if($origWidth < $origHeight && $origWidth > 450){
		$newHeight = 530;
		$newWidth = $origWidth * ($newHeight/$origHeight);

		$resizedImage = imagecreatetruecolor($newWidth, $newHeight);
		imagecopyresampled($resizedImage, $original, 0, 0, 0, 0, $newWidth, $newHeight, $origWidth, $origHeight);

	} elseif($origWidth > $origHeight && $origHeight > 530){
		$newWidth = 550;
		$newHeight = $origHeight * ($newWidth/$origWidth);

		$resizedImage = imagecreatetruecolor($newWidth, $newHeight);
		imagecopyresampled($resizedImage, $original, 0, 0, 0, 0, $newWidth, $newHeight, $origWidth, $origHeight);
	}
		// copy image to folder
		$res = imagejpeg($resizedImage, $path.$newName);

		if(!$res){
			$imageMsg = "Upload failed!";
			$err = true;
		} else {
			$imageMsg = "Upload successful";
		}

	} else {
		$imageMsg = "Wrong file type!";
		$err = true;
	}
