You can use DispatcherTimer class in order to change the images with respect to time.

Let me suggest you the easiest way. Name your images as numbers like 1.jpg,2.jpg,3.jpg etc and put them inside a folder.

Now you can use either random number class to pick the images in random order or can use the following method to get the sequentially:

DispatcherTimer picture_timer = new DispatcherTimer();
Random rnd = new Random();

picture_timer .Interval = new TimeSpan(0, 0, 3);
                   picture_timer .Tick += timer_Tick;
                   picture_timer .Start();

 void timer_Tick(object sender, object e)
        {
int num = rnd.Next(1, 13); // creates a number between 1 and 12
string image_source = "/Assets/"+num+".jpg";

}

  • Where exactly do i add this code on the MainPage.xaml or on the app.xaml – gnyangolo Apr 27 '16 at 11:59
  • You can declare first two lines of code as global above InitializeComponent(); and then its upto you you can add these lines in onnavigated to method: picture_timer .Interval = new TimeSpan(0, 0, 3); picture_timer .Tick += timer_Tick; picture_timer .Start(); and timer_tick itself is a function. – Bilal Amjad Apr 27 '16 at 12:01
