Java处理图片时报错：Can'n read input file，大佬们帮忙看看错在哪了？

代码：
package com.yxk.o2o.util;

import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import net.coobird.thumbnailator.Thumbnails;
import net.coobird.thumbnailator.geometry.Positions;

public class ImageUtil {
public static void main(String[] args) throws IOException{
String basePath = Thread.currentThread().getContextClassLoader().getResource("").getPath();

Thumbnails.of(new File("\\D:\\Testimg\\49J58PICDIi1024.jpg"))
.size(200, 200).watermark(Positions.CENTER,
ImageIO.read(new File(basePath+"\\25311700905481340002.jpg")),0.25f).outputQuality(0.8f)
.toFile("\\D:\\Testimg\\new49J58PICDIi1024.jpg");

}
}
