If you already know the picture name and type, this will work.
// The file
$filename = 'test.jpg';
$outfilename = "/path/picture.jpg";
// Set a maximum height and width
$width = 200;
$height = 200;
// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);
if ($width && ($width_orig < $height_orig))
$width = ($height / $height_orig) * $width_orig;
$height = ($width / $width_orig) * $height_orig;
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height,
imagejpeg($image_p, $outfilename, 100);
