Hi Brenny,

If you just want to copy this file to another location I would recommend using File.Copy instead of saving it again since that would just create a slightly lower quality JPG than you had to begin with.

In any case, to save an Image as JPG just use
Image.Save(path, ImageFormat.Jpeg);

Btw, when you say you get error message it helps if you tell us the exact errors (copy/paste).
Happy coding!
