Answer 1

If you want open your image in the pictureBox by a Default Winndows Editor try this;

//Create temporary file name
String TMP_IMAGE = "tempImage" +DateTime.Now.Millisecond +".bmp";

//get the folder of application
string PATH_APP =                
        System.IO.Path.GetDirectoryName(Application.ExecutablePath) + @"\tempImage\";

//Create a subFolder tempImage
Directory.CreateDirectory(PATH_APP);

//Save a new path in a variable
String NEW_PATH = PATH_APP + TMP_IMAGE;

//Save the image in the pictureBox in the new path and file name
pictureBox.Image.Save(NEW_PATH);

//Lunch the process with defaoul image editor in the comouter
ProcessStartInfo startInfo = new ProcessStartInfo(NEW_PATH);
Process.Start(startInfo);

You can try starting a process with a verb edit.

ProcessStartInfo startInfo = new ProcessStartInfo("C:\\image.png");
startInfo.Verb="edit";

Process.Start(startInfo);
