How can error reporting settings impact the functionality of PHP scripts, such as in the case of generating and displaying images using GD library functions?

Error reporting settings can impact the functionality of PHP scripts by suppressing error messages that could provide valuable information for debugging. In the case of generating and displaying images using GD library functions, errors related to image creation or manipulation may not be displayed if error reporting is set to a level that hides these messages. To ensure that errors related to image processing are displayed, error reporting settings should be adjusted to show all errors. 

// Set error reporting to display all errors
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Your GD library image generation and display code here
