here is the simpleimage code

class SimpleImage {
   var $image;
   var $image_type;
  
   function load($filename) {
       $image_info = getimagesize($filename);
      $this->image_type = $image_info[2];
      if( $this->image_type == IMAGETYPE_JPEG ) {
         $this->image = imagecreatefromjpeg($filename);
      } elseif( $this->image_type == IMAGETYPE_GIF ) {
         $this->image = imagecreatefromgif($filename);
      } elseif( $this->image_type == IMAGETYPE_PNG ) {
         $this->image = imagecreatefrompng($filename);
      }
   }
   function save($filename, $image_type=IMAGETYPE_JPEG, $compression=75, $permissions=null) {
      if( $image_type == IMAGETYPE_JPEG ) {
         imagejpeg($this->image,$filename,$compression);
      } elseif( $image_type == IMAGETYPE_GIF ) {
         imagegif($this->image,$filename);         
      } elseif( $image_type == IMAGETYPE_PNG ) {
         imagepng($this->image,$filename);
      }   
      if( $permissions != null) {
         chmod($filename,$permissions);
      }
   }
   function output($image_type=IMAGETYPE_JPEG) {
      if( $image_type == IMAGETYPE_JPEG ) {
         imagejpeg($this->image);
      } elseif( $image_type == IMAGETYPE_GIF ) {
         imagegif($this->image);         
      } elseif( $image_type == IMAGETYPE_PNG ) {
         imagepng($this->image);
      }   
   }
   function getWidth() {
      return imagesx($this->image);
   }
   function getHeight() {
      return imagesy($this->image);
   }
   function resizeToHeight($height) {
      $ratio = $height / $this->getHeight();
      $width = $this->getWidth() * $ratio;

      $height = $this->getheight() * $scale/100; 
      $this->resize($width,$height);
   }
   function resize($width,$height) {

Hi there,
Myself and a buddy at work were dumbfounded by a similar situation not too long ago. Our current working theory is that the GD library's imagecreate****** methods first turn any image into a bitmap, could be wrong but it explains all the extra memory usage.

Anycase, your best bet is to dynamically increase the memory limit for your script with an adaptation of the following:

$imageInfo = getimagesize("$file");
    $memoryNeeded = round(($imageInfo[0] * $imageInfo[1] *
    $imageInfo['bits'] * $imageInfo['channels'] / 8 + Pow(2, 16)) * 1.65);
    if (function_exists('memory_get_usage') && memory_get_usage() +
    $memoryNeeded > (integer) ini_get('memory_limit') * pow(1024, 2)) 
    {
        ini_set('memory_limit', (integer) ini_get('memory_limit') +
        ceil(((memory_get_usage() + $memoryNeeded) - (integer)
        ini_get('memory_limit') * pow(1024, 2)) / pow(1024, 2)) . 'M');
    }
    echo("Memory Need:".$this->ConvertSize($memoryNeeded)." <br/>");
