You have mentioned
$sql = "INSERT INTO images ( imageData) VALUES ('$imageData')";
besides you have also mentioned
  $sql = "SELECT * FROM images";
which indicates you have just one field imageData in the images table - of course there could be an id field.
Does it also mean you have only one image in the images tables.
Because you have mentioned
   $sql = "SELECT * FROM images";
        header("Content-type: image/jpeg");
        echo mysql_result($result, 0,'imageData');
if there are multiple rows in the table you have to iterate through the result array to
display images one by one.
I think this is where you are failing.

Try to display it like this:

$db_selected = mysql_select_db('upload', $link);

if (!$db_selected) {
    die ('Database error : ' . mysql_error());
}

        $sql = "SELECT * FROM images";
        $result = mysql_query($sql);
        $row = mysql_fetch_array($result);
        
        header("Content-type: image/jpeg");
        echo $row['imageData'];
 
     
?>

BUT I would definetely recommend to store the images as files having a link in the database to the path where they are. The database can rapidly grow to big size. If that is just for learning purposes, the code provided should be ok.
