Welcome to the ODK forum, @Mohammad_Odeh! We're glad you're here. When you get a chance, please introduce yourself on this forum thread. I'd also encourage you to add a picture as your avatar because it helps build community!
The default image widget (with type = image) can be modified to be a self portrait image and use the camera on the side of the phone with the screen. To do this, add an appearance column to your XLSForm with a value of new-front for the question.
