accessing one control of one page to another page

Hello,

I am working on xamarin forms since last month.But now I struck up with a problem.
I created a ContentView that is to be used in a ContentPage and I am able to access the ContentView in any ContentPage I want to.
But,now I want a control of one view to be used in another view or page.For example I want an Image of one View to be accessed in antoher view.

Thanks in advance.
