imagecreatefromjpeg problem with memory

Question

Hello everyone I am trying to resize an image of 700kb with imagecreatefromjpeg.

This gives the error: Fatal error: Allowed memory size of 25165824 bytes exhausted (tried to allocate 9356 bytes)

First the memory_limit was 8M then we set this to 24 M but then it still gives the error. Is this a memory leak? What could have happened? We restarted apache already.

Here is some code for those who are interested:

function getResizedBackgroundImageURL($afb="",$params="") {
#1. Verwijder webroot
$filename=C_Settings::getFileRoot().str_replace(C_Settings::getWebRoot(),"",$afb);
$i=strrpos($filename,".");
if ($i!==FALSE) {
 $ext=substr($filename,$i);
 $basefilename=substr($filename,0,$i);

 #Parse width/height params
 $a=explode("&",$params);
 foreach($a as $attr) {
  $b=explode("=",$attr);
  if ($b[0]=="w") {
   $w=$b[1];
  } elseif ($b[0]=="h") {
   $h=$b[1];
  }
 }

 if (!is_numeric($w)) {
   die("Missing param w for getResizedBackgroundImageURL");
 }

 if (!is_numeric($h)) {
   die("Missing param h for getResizedBackgroundImageURL");
 }

 #Compose new filename
 $newFilename=$basefilename."_w".$w."_h".$h.$ext;
 #See if the resized image exists
 if (!file_exists($newFilename)) {
    if (is_file($filename)) {
     if($ext==".jpg" || $ext==".jpeg"){

      $image_org=imagecreatefromjpeg($filename);


     }
     if($ext==".gif") {
      $image_org=@imagecreatefromgif($filename);
     }

     if ($image_org) {
      list($wp,$hp,$type,$attr)=getimagesize($filename);
      $hfactor=$hp/$h;
      $wfactor=$wp/$w;
      if ($hfactor > $wfactor) {
      $factor=$hfactor;
     } else {
      $factor=$wfactor;
     } 
    if($wp > $w || $hp > $h) {
        $image_w=$wp/$factor;
        $image_h=$hp/$factor;
        }else{
         #if image fits the given boundaries, do not resize
         $image_w=$wp;
        $image_h=$hp;          
        }
        //Note: PHP with GD2.0 required for imagecreatetruecolor
        $img_copy=imagecreatetruecolor($image_w, $image_h);
        imagecopyresampled($img_copy, $image_org, 0, 0, 0, 0, $image_w, $image_h, $wp, $hp);

      if (@imagejpeg($img_copy, $newFilename, 80)) {
       chmod($newFilename,0777);
      } else {
       echo("<b>Error: </b>Unable to create image $newFilename. Check directory permissions.");
      } 

       imagedestroy($image_org);
      imagedestroy($img_copy);
    }
  }      
 }
 $newURL=C_Settings::getWebRoot().str_replace(C_Settings::getFileRoot(),"",$newFilename);
 return $newURL;  
}

}

Increase your memory until you have enough and make sure you use imagedestroy() when your done with your processing.

ini_set("memory_limit","10000M");
