What are the advantages and disadvantages of using PHP scripts to add watermarks to images compared to using image editing software with batch processing capabilities?

When adding watermarks to images, using PHP scripts can be advantageous as it allows for automation and can be integrated into existing web applications easily. However, using image editing software with batch processing capabilities may provide more control over the placement and appearance of the watermark. 

<?php
// Function to add watermark to an image
function addWatermark($imagePath, $watermarkPath, $outputPath) {
    $image = imagecreatefromjpeg($imagePath);
    $watermark = imagecreatefrompng($watermarkPath);

    $imageWidth = imagesx($image);
    $imageHeight = imagesy($image);
    $watermarkWidth = imagesx($watermark);
    $watermarkHeight = imagesy($watermark);

    $destX = $imageWidth - $watermarkWidth - 10;
    $destY = $imageHeight - $watermarkHeight - 10;

    imagecopy($image, $watermark, $destX, $destY, 0, 0, $watermarkWidth, $watermarkHeight);

    imagejpeg($image, $outputPath);

    imagedestroy($image);
    imagedestroy($watermark);
}

// Usage
addWatermark('image.jpg', 'watermark.png', 'output.jpg');
?>
