What are the potential pitfalls of storing image data in a database and how can they be mitigated when creating image navigation functionality?

Potential pitfalls of storing image data in a database include increased storage space usage and slower retrieval times. To mitigate these issues when creating image navigation functionality, it is recommended to store images on the server file system and only store their file paths in the database. 

// Store image path in the database
$imagePath = "images/image.jpg";
$query = "INSERT INTO images (image_path) VALUES ('$imagePath')";
$result = mysqli_query($connection, $query);

// Retrieve image path from the database
$query = "SELECT image_path FROM images WHERE id = $imageId";
$result = mysqli_query($connection, $query);
$imagePath = mysqli_fetch_assoc($result)['image_path'];

// Display image using the retrieved path
echo "<img src='$imagePath' alt='Image'>";
