Cacheing Images

[comptech520]

Does anyone know any good scripts to create thumbnails from an orignial image, and cache it in a different directory?

Thanks

$max_height_or_width = 120; // in pixels
$photo_name = '123456.jpg';
$full_path_photo = 'path to big-photodirectory/'.$photoname;
$full_path_thumb = 'path to thumbdirectory/'.$photoname;

$src_img = imagecreatefromjpeg( $full_path_photo );
$sizesrc = getimagesize( $full_path_photo );

if ($sizesrc[0] > $sizesrc[1])
{
$dest_x = $max_height_or_width;
$factor = $sizesrc[0]/$max_height_or_width;
$dest_y = $sizesrc[1]/$factor;
}
else
{
$dest_y = $max_height_or_width;
$factor = $sizesrc[1]/$max_height_or_width;
$dest_x = $sizesrc[0]/$factor;
}

$dst_img = imagecreatetruecolor($dest_x, $dest_y);
imagecopyresampled( $dst_img, $src_img, 0, 0, 0, 0, $dest_x, $dest_y, $sizesrc[0], $sizesrc[1] );
imagejpeg( $dst_img, $full_path_thumb );
imagedestroy( $src_img );
imagedestroy( $dst_img );
