How can the PHP configuration settings impact the compatibility of a photo album script with different PHP versions?

The PHP configuration settings can impact the compatibility of a photo album script with different PHP versions by affecting the availability of certain functions or features that the script relies on. To ensure compatibility, it's important to check the PHP version requirements of the script and adjust the configuration settings accordingly. 

// Example of adjusting PHP configuration settings for compatibility with a photo album script
if (version_compare(PHP_VERSION, '7.0.0', '<')) {
    // Adjust configuration settings for older PHP versions
    ini_set('memory_limit', '256M');
    ini_set('max_execution_time', 300);
} else {
    // Configuration settings for PHP 7 and above
    ini_set('memory_limit', '512M');
    ini_set('max_execution_time', 600);
}
