Forgive me for being a dumb Perl newbie...
I've gone through your code, and it all makes sense except for the confess stuff... what does that mean?

I'm using PerlScript in an ASP page, and tried out your sub... here is what my page looks like:

<%@ LANGUAGE = PerlScript 


my $globalPreviewMaxDimension = 100;

sub util_photo_GenerateThumbnail
{
  my ($source, $destination) = @_;

  my $preview = Image::Magick->new;

  my $x = $preview->Read ($source); confess "$x" if "$x";

  my ($xSize, $ySize) = $preview->Get ('width', 'height'); # Get the p
+ictures dimensions
    
  #
  #  Calculate dimensions of thumbnail
  #
  my $scaleFactor;
  my $previewX;
  my $previewY;

  #
  #  Only scale if either axis is larger than the preview size
  #
  if ($xSize > $globalPreviewMaxDimension || $ySize > $globalPreviewMa
+xDimension)
  {
    if ($xSize > $ySize) 
    {
      $scaleFactor = $globalPreviewMaxDimension / $xSize;
      $previewX    = $globalPreviewMaxDimension;
      $previewY    = int ($ySize * $scaleFactor);
    }
    else 
    {
      $scaleFactor = $globalPreviewMaxDimension / $ySize;
      $previewY    = $globalPreviewMaxDimension;
      $previewX    = int ($xSize * $scaleFactor);
    }

    $x = $preview->Scale  (width=>$previewX, height=>$previewY); confe
+ss "$x" if "$x";

    $xSize = $previewX;
    $ySize = $previewY;
  }
