The absence of the gd-lib in PHP can impact the functionality of image functions as it is a library required for image processing. To solve this issue, you need to ensure that the gd extension is enabled in your PHP configuration or install it if it's missing. 

// Check if the gd extension is enabled
if (!extension_loaded('gd')) {
    echo 'GD extension is not enabled. Please enable it for image processing functionality.';
} else {
    // GD extension is enabled, proceed with image processing
    // Your image processing code here
}
