<Image Source={Binding imgSource} />     

Answer 1

I presume that you are using a platform specific component to generate images. This component either stores the generated image into the filesystem or returns a binary representation in memory.

To convert a file into an ImageSource, you would use ImageSource.FromFile(). To convert a stream, use ImageSource.FromStream().

You can find the APIs here and some great documentation there.

In your case above, the BindingContext (whether that's a page or a ViewModel does not matter) will have to expose a public property of type ImageSource and returns the converted image using either of the methods above.
