MySQL QUERY for photo ranking - mysql

Question

I have 2 tables:
CREATE TABLE `psPhotosRating` (
`id_photo_rating` int(11) NOT NULL,
`id_user` int(11) NOT NULL,
`id_uploaded_files` int(11) NOT NULL,
`rating` int(2) NOT NULL,
`timestamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
CREATE TABLE `psUploadedFiles2` (
`id_uploaded_files` int(10) UNSIGNED NOT NULL,
`enable` char(1) COLLATE utf8_unicode_ci NOT NULL DEFAULT '0',
`id_user` int(11) NOT NULL DEFAULT '0',
`file_path` varchar(150) COLLATE utf8_unicode_ci NOT NULL,
`file_name` varchar(75) COLLATE utf8_unicode_ci NOT NULL,
`creation_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`category` bigint(20) NOT NULL DEFAULT '0',
`tags` text COLLATE utf8_unicode_ci,
`description` mediumtext COLLATE utf8_unicode_ci,
`promo_in_front` char(1) COLLATE utf8_unicode_ci NOT NULL DEFAULT '0',
`count` bigint(20) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
ALTER TABLE `psPhotosRating`
ADD PRIMARY KEY (`id_photo_rating`);
ALTER TABLE `psPhotosRating`
MODIFY `id_photo_rating` int(11) NOT NULL AUTO_INCREMENT;
ALTER TABLE `psUploadedFiles2`
MODIFY `id_uploaded_files` int(10) UNSIGNED NOT NULL AUTO_INCREMENT;
COMMIT;
psUploadedFiles2 - this is the "photo database"
psPhotosRating - table with votes cast for each photo from psUploadedFiles2
Not every picture has votes.
I need a SQL query displaying a list of images (psUploadedFiles2) sorted by the psPhotosRating rank (number of votes cast).
Does anyone know how to do it?

I think you can just join here second table and count results:
SELECT count(rat.id_uploaded_files ) as rating, ps.*
FROM psUploadedFiles2 ps
JOIN psPhotosRating rat ON ps.id_uploaded_files = rat.id_uploaded_files
ORDER BY rating DESC;
