What are the potential pitfalls of not properly linking uploaded images to user profiles in a PHP application?

If images uploaded by users are not properly linked to their profiles in a PHP application, it can lead to confusion and disorganization. Users may not be able to easily access or manage their uploaded images, and there could be security risks if images are not properly associated with the correct user. To solve this issue, ensure that each uploaded image is linked to the corresponding user profile by storing the user's ID along with the image file path in the database.

// Assuming $userId is the ID of the user uploading the image
// and $imagePath is the file path where the image is stored

// Insert the image file path and user ID into the database
$query = "INSERT INTO images (user_id, file_path) VALUES ($userId, '$imagePath')";
// Execute the query

// Retrieve all images associated with a specific user
$userId = 1; // Example user ID
$query = "SELECT * FROM images WHERE user_id = $userId";
// Execute the query and display the images
