How can PHP developers efficiently handle database queries for image galleries to ensure a sequential display of images?

To ensure a sequential display of images in an image gallery, PHP developers can efficiently handle database queries by sorting the images based on a unique identifier, such as an auto-incremented ID. This way, the images will be displayed in the order they were added to the database. 

// Assuming $db is the database connection object
$query = "SELECT * FROM images ORDER BY id ASC";
$result = $db->query($query);

if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        // Display each image in the gallery
        echo '<img src="' . $row['image_url'] . '" alt="' . $row['image_alt'] . '">';
    }
} else {
    echo 'No images found.';
}
