将图像保存到另一台服务器

Question

我目前使用以下功能创建并保存自定义图像。这完美地运行并将图像保存到我的服务器。

function merge($filename_x, $filename_y, $filename_result) {

 // Get dimensions for specified images
 list($width_x, $height_x) = getimagesize($filename_x);
 list($width_y, $height_y) = getimagesize($filename_y);

 // Create new image with desired dimensions
 $image = imagecreatetruecolor($width_x + $width_y, $height_x);

 // Load images and then copy to destination image
 $image_x = imagecreatefromjpeg($filename_x);
 $image_y = imagecreatefromgif($filename_y);

 imagecopy($image, $image_x, 0, 0, 0, 0, $width_x, $height_x);
 imagecopy($image, $image_y, $width_x, 0, 0, 0, $width_y, $height_y);

 // Save the resulting image to disk (as JPEG)
 imagejpeg($image, $filename_result);

 // Free memory
 imagedestroy($image);
 imagedestroy($image_x);
 imagedestroy($image_y);
}

使用：

$img1 = '/folder1/folder2/image1.gif';
$img2 = '/folder1/folder2/image2.gif';
$destination = '/dirabc/dirdef/finalImage.jpeg';
merge($img1 , $img2 , $destination );

问题是，如何将此图像保存到我拥有的另一台服务器上？
