PHP Error: mysql_fetch_array() expects parameter 1 to be resource, boolean given

I have checked the code twice and I have also checked the titles in the table also and they match, I have probably been looking at the code for too long and it may be hard for me to find the error.

Lines 13-34

$albums_query = mysql_query("
SELECT `albums`.`album_id`, `albums`.`timestamp`, `albums`.`name`, LEFT(`albums`.`description`, 50) as `description`, COUNT         (`images`.`images_id`) as `image_count`
FROM `albums`
LEFT JOIN `images`
ON `albums`.`album_id` = `images`.`album_id`
WHERE `albums`.`user_id` = ".$_SESSION['user_id']."
GROUP BY `albums`.`album_id` 
");

while ($albums_query = mysql_fetch_assoc($albums_query)) {
    $albums[] = array(
        'id' => $albums_row['album_id'],
        'timestamp' => $albums_row['timestamp'],
        'name' => $albums_row['name'],
        'description' => $albums_row['description'],
        'count' => $albums_row['image_count']
    );
}

return $albums ;

}

You're overriding your query result with a row of data:

$albums_query = mysql_fetch_assoc($albums_query)

Should be:

 $albums_row = mysql_fetch_assoc($albums_query)

(probably)
