In what scenarios would it be preferable to store images in a MySQL database rather than on an FTP server when building a gallery in PHP?

Storing images in a MySQL database can be preferable when you want to ensure data integrity and maintain a direct relationship between the images and other related data in the database. This can simplify data management and retrieval processes, especially if you need to perform complex queries or maintain referential integrity. However, storing images in a database can increase its size and potentially impact performance, so it's important to weigh the pros and cons based on your specific requirements. 

// Sample PHP code to store images in a MySQL database

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

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

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

// Insert image into database
$image = file_get_contents("path/to/image.jpg");
$sql = "INSERT INTO images (image_data) VALUES (?)";
$stmt = $conn->prepare($sql);
$stmt->bind_param("b", $image);
$stmt->execute();

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