Wow, that's weird - that looks almost exactly like some code we just wrote
for a project.


function ConvertImageToThumbnail($inPath, $outPath) {
    // Convert the image at the path specified by $inPath
    // to a thumbnail image at the path specified by $outPath.

	// Get the width and height of the actual image.
    list($width, $height) = getimagesize($inPath);

	// How big should the thumbnail be?
    if( (119.0/$width) > (119.0/$height) )
        $scale = 119.0/$height;
    else
        $scale = 119.0/$width;

    $newwidth = $width * $scale;
    $newheight = $height * $scale;

	// Create a new thumbnail image of the correct size.
    $thumb = imagecreatetruecolor($newwidth, $newheight);

	// Load the original image.
    $source = imagecreatefromjpeg($inPath);

 
imagecopyresampled($thumb,$source,0,0,0,0,$newwidth,$newheight,$width,$heigh
t);

	// Write out the thumbnail as a JPEG.
    imagejpeg($thumb, $outPath);
}  // ConvertImageToThumbnail


Have a good Thanksgiving everyone,
