What are potential pitfalls to avoid when rotating images and quotes using PHP?

Potential pitfalls to avoid when rotating images and quotes using PHP include not properly handling file paths, not validating user input, and not securely storing sensitive information. To prevent these issues, make sure to sanitize and validate user input, use absolute file paths when rotating images, and store sensitive information like database credentials securely. 

// Example of sanitizing and validating user input
$user_input = $_POST['user_input'];
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);
if(!empty($sanitized_input)){
    // Proceed with rotating images or displaying quotes
} else {
    // Handle error or display message to user
}
