What are the potential pitfalls of using a random script to display images stored in different database columns in PHP?

The potential pitfalls of using a random script to display images stored in different database columns in PHP include security vulnerabilities such as SQL injection attacks, inefficient code execution due to lack of optimization, and potential data inconsistency issues. To solve this problem, it is recommended to use prepared statements to prevent SQL injection, optimize the code for better performance, and ensure data consistency by properly structuring the database schema. 

// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Prepare and execute SQL query to fetch images
$stmt = $conn->prepare("SELECT image_column FROM images_table ORDER BY RAND() LIMIT 1");
$stmt->execute();
$stmt->bind_result($image);

// Display the image
while ($stmt->fetch()) {
    echo '<img src="data:image/jpeg;base64,' . base64_encode($image) . '" />';
}

// Close connection
$stmt->close();
$conn->close();
