[Resolved] Creating 1000's of thumbnails (not a howto)

[wdglide]

I am using the code below to loop thru the contents of a directory and make a thumbnail of all the images. The directory contains only .jpg images.

Two questions:

1. Is there a better method of doing this? This process takes too long. It is stopping (unfinished) at 10 minutes.

2. Should I be expecting an email from my host regarding processor hogging. Or is this a relatively light process?

   // error_reporting(E_ALL);
   set_time_limit (600);
   /* Adapted from [url]http://uk2.php.net/manual/en/ref.image.php[/url]
    * resizeToFile resizes a picture and writes it to the harddisk
    * $sourcefile = the filename of the picture that is going to be resized
    */
   function resizeToFile ($sourcefile) {
   	/* Get the dimensions of the source picture */
       $picsize=getimagesize("$sourcefile");
       $source_x  = $picsize[0];
       $source_y  = $picsize[1];
       $source_id = imageCreateFromJPEG("$sourcefile");
   	/* Create a new image object (not neccessarily true colour) */
       $target_id=imagecreatetruecolor(160, 125);
   	/* Resize the original picture and copy it into the just created image object. */
       $target_pic=imagecopyresampled($target_id,$source_id,0,0,0,0,160,125,$source_x,$source_y);
   	/* Create a jpeg with the quality of 30 out of the image object "$target_pic". This will be saved as $targetfile */
       $targetfile = str_replace(".jpg","_small.jpg",$sourcefile);
   	imagejpeg ($target_id,$targetfile,30);
       return true;
   } 
   
   /* open photos directory */
   $handle = opendir('photos'); 
   /* loop through it  */
   while (false !== ($file = readdir($handle))) { 
   	/* if not already a thumbnail */
   	if ($file != "." && $file != ".." && substr($file,-10) != "_small.jpg") { 
   		/* create a thumbnail */
   		resizeToFile ("photos/" . $file);
   	}
   }
   /* close directory  */
   closedir($handle);

that should be fine to run. the only reason it stops after 10 minutes is because of the top line:
set_time_limit (600);
just put
set_time_limit(0); // for unlimited
