	{
		
		 
		
		$myImage = imagecreatefromjpeg($_FILES["filUpload"]["tmp_name"]);
		$myCopyright = imagecreatefrompng('../../myfile/1.png');

		move_uploaded_file($_FILES["filUpload"]["tmp_name"],"../../myfile/".$_FILES["filUpload"]["name"]);
		$destWidth = imagesx($myImage);
		$destHeight = imagesy($myImage);
		$srcWidth = imagesx($myCopyright);
		$srcHeight = imagesy($myCopyright);

		$destX = ($destWidth - $srcWidth) / 3;
		$destY = ($destHeight - $srcHeight) / 1;
		$white = imagecolorexact($myCopyright, 255, 255, 255);
		imagecolortransparent($myCopyright, $white);

		imagecopymerge($myImage, $myCopyright, $destX, $destY, 0, 0, $srcWidth, $srcHeight, 50);

		imagejpeg($myImage,"../../myfile/".$_FILES["filUpload"]["name"]);
		imagedestroy($myImage);
		imagedestroy($myCopyright);
