Button with Image

Hi guys,

I want to make a button with an image. If I use this annotation it works:

<Button Text="bla bla bla" Clicked="Func21" Image="image.png"/>

Meanwhile if the path of the image is more complex it doesn't work. So this doesn't work:

<Button Text="bla bla bla" Clicked="Func21" Image="folder1/folder2/folder3/image.png"/>

So how can I specify a complex path?
