What potential issues could arise when uploading images and inserting data into a database using PHP?

One potential issue that could arise when uploading images and inserting data into a database using PHP is the risk of SQL injection attacks if input data is not properly sanitized. To prevent this, it is important to use prepared statements with parameterized queries to securely insert data into the database. 

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Prepare a SQL statement with placeholders
$stmt = $pdo->prepare("INSERT INTO images (image_name, image_data) VALUES (:image_name, :image_data)");

// Bind parameters
$stmt->bindParam(':image_name', $image_name);
$stmt->bindParam(':image_data', $image_data, PDO::PARAM_LOB);

// Execute the statement
$stmt->execute();
