求救http 500内部服务器错误
本人写了个水印处理图片：在本地debug时没有任何问题：
但是上传至服务器运行时就会报 http 500内部服务器错误
private void UploadImg(string newFileName)
{
//上传大图片
string txt = this.txtProcess.Text;
if (txt == "")
{
txt = "哈哈";
}
string path = Server.MapPath("~/goods/");
//对图片进行水印处理
makeWatermark(10, 10, txt, this.fileupImage.PostedFile.FileName, newFileName, path);
//生成缩略图并上传
string s = Server.MapPath("~/goods/" + newFileName);
string paths = Server.MapPath("~/goods/sGoods/");
SmallPic(s, paths + newFileName, 150, 200);

} --------------------编程问答-------------------- 本地正常但是传上去不正常的，检查：
（1）相对路径、启用父路径、路径权限
（2）数据库权限、配置
（3）服务器是否安装所需组件，尤其是3方组件；asp.net版本
（4）查看日志，启用错误输出，帮助分析。 --------------------编程问答--------------------
我没用什么地第三方组件啊
（4）查看日志，启用错误输出，帮助分析。？这个怎么搞？
补充：.NET技术 , ASP.NET
