Sounds like you're basically asking "How do I do binding". A good read is: http://msdn.microsoft.com/en-us/magazine/hh852595.aspx and nearly any other Binding resource you find out there.

In your case you will need an object that has a Title and a ImageSource property that is set as the DataContext of the control (or one of its parents like the PhoneApplicationPage ). You can set the DataContext from your code behind (or in XAML) (if you're on the Page then you can simple set DataContext = ... .
