title: How do I center one image over another in React Native
body: <p>I'm trying to make a clock component with a face image and a needle centered on the clock in React Native. 
   does not allow embedding other Images.
  I found a few posts for centering text over images but cannot find any way do center Image over images.</p>
  
  <p>Edit:
  I'm trying to find a way that avoids giving absolute position so the component can be dynamically sized.</p>
