Image upload script exhausting memory

[petenaylor]

Hi all

 

I have a script that takes up to 3 images and resizes them. It works except for if you try and upload images over roughly 500kb. I then get the message:

 

Fatal error: Allowed memory size of X bytes exhausted (tried to allocate Y bytes)

 

Here's a snippet of the code for one image:

 

// Process image 1 :

if(!empty($_FILES['image1']['name'])) {
$imagelarge = $_FILES['image1']['tmp_name'];
$imagelargemain = $_FILES['image1']['name'];
$pathInfo = pathinfo($imagelargemain); 
$rand = rand(1, 100000000000000); 
$name = $rand . '.' . $pathInfo['extension']; 
$src = imagecreatefromjpeg($imagelarge);
list($width,$height)=getimagesize($imagelarge);
if ($width > $height) {
$newwidth=600;
$newheight=($height/$width)*$newwidth;
}
elseif ($height > $width) {
$newheight=400;
$newwidth=($width/$height)*$newheight;
}
$center_x = (600/2)-($newwidth/2);
$center_y = (400/2)-($newheight/2);
$tmp=imagecreatetruecolor(600,400);
$white = imagecolorallocate($tmp, 255, 255, 255);
imagefill($tmp, 0, 0, $white);
imagecopyresampled($tmp,$src,$center_x,$center_y,0,0,$newwidth,$newheight,$width,$height);
$filename = WEB_UPLOAD."images/adverts/". $name;
imagejpeg($tmp,$filename,100);
imagedestroy($src);
imagedestroy($tmp);
$image_sql = mysql_query("UPDATE `adverts` SET image1 ='".$name."' WHERE id='".$insertid."'") or die ("Error updating database");	
}

 

Any ideas why this happens?

 

Many thanks

 

Pete

this might not have anything to do with your script it might be worth checking and increasing your max upload limit and i would increase the script timeout limit too - do this in your php.ini
