Are there any security concerns to consider when using image buttons in PHP forms?

When using image buttons in PHP forms, one security concern to consider is that the value of the button may be manipulated by a user to submit unexpected data. To prevent this, you can check the value of the image button in your PHP form processing code to ensure it matches the expected value. 

// Check if the image button value matches the expected value
if(isset($_POST['image_button']) && $_POST['image_button'] == 'submit_button_value') {
    // Process the form data
} else {
    // Handle unexpected form submission
    echo "Invalid form submission";
}
