How can developers ensure code readability and maintainability in PHP scripts for image watermarking, especially when using custom classes and methods?

To ensure code readability and maintainability in PHP scripts for image watermarking, developers can utilize custom classes and methods to encapsulate related functionality and improve code organization. By breaking down the watermarking process into smaller, reusable components, developers can easily modify and extend the functionality without affecting other parts of the codebase. Additionally, documenting the purpose of each class and method, as well as providing clear and concise variable names, can further enhance code readability and maintainability. 

class ImageWatermarker {
    private $image;
    
    public function __construct($imagePath) {
        $this->image = imagecreatefromjpeg($imagePath);
    }
    
    public function addWatermark($watermarkPath, $x, $y) {
        $watermark = imagecreatefrompng($watermarkPath);
        imagecopy($this->image, $watermark, $x, $y, 0, 0, imagesx($watermark), imagesy($watermark));
        imagedestroy($watermark);
    }
    
    public function saveImage($outputPath) {
        imagejpeg($this->image, $outputPath);
        imagedestroy($this->image);
    }
}

// Example of usage
$imageWatermarker = new ImageWatermarker('input.jpg');
$imageWatermarker->addWatermark('watermark.png', 10, 10);
$imageWatermarker->saveImage('output.jpg');
