What are the potential pitfalls of using img_id to link images to content in PHP?

Using img_id to link images to content in PHP can lead to potential pitfalls such as security vulnerabilities if the img_id is not properly sanitized, the possibility of broken links if the img_id changes or is deleted, and difficulty in maintaining and updating the links if there are multiple references to the same image. To solve this issue, it is recommended to store the image path or URL directly in the database instead of relying on an img_id. 

// Store image path or URL directly in the database
$image_path = "path/to/image.jpg";

// Retrieve image path from the database
$query = "SELECT image_path FROM images WHERE image_id = :img_id";
$stmt = $pdo->prepare($query);
$stmt->bindParam(':img_id', $img_id);
$stmt->execute();
$image_path = $stmt->fetchColumn();

// Display the image
echo "<img src='$image_path' alt='image'>";
