Image gallery problem

[wrathican]

ive created a simple image gallery:

 

the user can upload an image and the script will create a thubnail and add it to the DB

 

a user recently complained to me that he gets this error:

Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 2592 bytes) in /home/fhlinux162/m/members.ls12style.co.uk/user/htdocs/includes/functions.php on line 146

 

it seems that is is just this user that gets this error. i asked him to mail me one of the images he was trying to use so i could try it.

 

i got the same error

 

it seems as though the GD functions do not recognise the image as a propper image and the script just fails.

 

heres the function that handles the thumbnail creation:

<?php

function createThumb($result, $picWidth, $imgDir) {
$poo = array();
if ($result == false) {
	//file could not be uploaded
	$poo[0] = false;
	$poo[1] = 1;
	return $poo;
}else{
	//file was uploaded. create thumbnail
	//pathinfo
	$file = pathinfo($result);
	//find the .ext
	$ext = $file['extension'];
	//strip .ext to lower
	$ext = strtolower($ext);
	//get image sizes
	$sizes = getimagesize($result);
	//ratio
	$ratio = $sizes[0]/$sizes[1];
	//create new height
	$newHeight = round($picWidth/$ratio);
	//create true colour image		
	$srcImg = imagecreatetruecolor($picWidth, $newHeight);
	if($ext == 'jpg' || $ext == 'jpeg') {
		$tmpImg = imagecreatefromjpeg($result);
	}elseif($ext == 'png') {
		$tmpImg = imagecreatefrompng($result);
	}elseif($ext == 'gif') {
		$tmpImg = imagecreatefromgif($result);
	}else{
		$poo[0] = false;
		$poo[1] = 2;
		return $poo;
	}
	//create destination image filename
	//get filename
	$name = $file['basename'];
	//dest filename
	$dstFile = $imgDir . $name;
	imagecopyresampled($srcImg, $tmpImg, 0, 0, 0, 0, $picWidth, $newHeight, $sizes[0], $sizes[1]);
	//save image
	if($ext == 'jpg' || $ext == 'jpeg') {
		imagejpeg($srcImg, $dstFile, 100);
	}elseif($ext == 'png') {
		imagepng($scrImg, $dstFile, 100);
	}elseif($ext == 'gif') {
		imagegif($srcImg, $dstFile, 100);
	}else{
		$poo[0] = false;
		$poo[1] = 3;
		return $poo;;
	}

	$killSrc = imagedestroy($srcImg);
	$killTmp = imagedestroy($tmpImg);
	if($killSrc != false && $killTmp != false){
		$killOld = unlink($result);
		if($killOld != false){
			return $name;
		}else{
			$poo[0] = false;
			$poo[1] = 4;
			return $poo;
		}
	}else{
		$poo[0] = false;
		$poo[1] = 5;
		return $poo;
	}
}
}

?>

 

any suggestions are welcome

I'm also having a similar issue, however it only happens when I try to upload an image thats 1MB or higher
