How can I do to get the next row in a table?

`image_id` int(11) NOT NULL auto_increment
`image_title` varchar(255) NOT NULL
`image_text` mediumtext NOT NULL
`image_date` datetime NOT NULL
`image_filename` varchar(255) NOT NULL

If the current image is 3 for example and the next one is 7 etc. this won’t work:

$query = mysql_query("SELECT * FROM images WHERE image_id = ".intval($_GET['id']));
echo $_GET['id']+1;

How should I do?

thanks
