PHP - broken image displaying from database

Every time a user submits a picture for their "profile pic" it will display as a "broken image" and I noticed that when I physically insert an image into the mysql data base and display it, it works perfectly and the size of the file changes to "BLOB - KiB" instead of MB. But when I insert that same image into the database using my "upload file", that image turns to "BLOB MB" and doesn't display on the website. I saw some post about this and they said to remove the "addslashes" from the variable and i did that but it still didn't work. So what i wan't to do is display the image from the database that was submitted by the user. It works when you physically insert it into the database without a file but if you do it with one, it doesn't work. Here is a screen shot of the database structure, upload file, and retrieving file.

PHP Upload file

session_start();
if(empty($_FILES) && empty($_POST) && isset($_SERVER['REQUEST_METHOD']) && strtolower($_SERVER['REQUEST_METHOD']) == 'post') { //catch file overload error...
    $postMax = ini_get('post_max_size'); //grab the size limits...
    echo "<p style=\"color: #F00;\">\nPlease note files larger than {$postMax} will result in this error!</p>"; // echo out error and solutions...
    return $postMax;
}
if(isset($_COOKIE['username'])) {
    if($_SESSION['came_from_upload'] != true) {
        setcookie("username", "", time() - 60 * 60);
        $_COOKIE['username'] = "";
        header("Location: developerLogin.php");
        exit;
    }
    error_reporting(E_ALL & ~E_NOTICE);
    if($_SERVER['REQUEST_METHOD'] == "POST") {
        $token = $_SESSION['token'];
        $userid = $_SESSION['id'];
        $fullname = addslashes(trim($_POST['fullname']));
