Using system calls to create thumbnails

bpp198

Hi all,
Having a bit of trouble creating thumbnails. I have no access to jpeg or gif functions in my current PHP build, and cannot change this (shared server).

I am using system commands to create the thumbnails. This code was working perfectly one day, and then for no apparent reason (i promise), it stopped working. The resulting thumbnail image - $id_tn.jpg - was a 0k file.

Any ideas? The code is shown below.

Thanks,
Benji.

CODE:

// save photo
$photo_location = "/home/badders/public_html/dad/photos/".$photo_id.".jpg";
$tn_location = "/home/badders/public_html/dad/photos/".$photo_id."_tn.jpg";
$tmpimg = tempnam("/tmp", "MKPH");
move_uploaded_file($photo, $photo_location);

  // create & save thumbnail
    //$tnw = 100;
    //$tnh = 100;

    // use *nix commands to create tn
      system("djpeg $photo_location >$tmpimg");
      system("pnmscale -xysize 100 100 $tmpimg | cjpeg -smoo 10 -qual 50 >$tn_location");

ALWAYS SEARCH THE ARCHIVES BEFORE POSTING.

Yeah yeah I know. Here is the problem, the pnmscale util was not in the /usr/bin directory.
