Answer 1

Get this picture from *http.Request, by key (in this case "file"), then create a file and copy it there from the form

file, fileHeader, err := r.FormFile("file")
      if err != nil {
        log.Fatal(err)
      }
      defer file.Close()
      f, err := os.Create("filepath"))
      if err != nil {
        log.Fatal(err)
        return  err
      }
