title: image cropped as a triangle on webpage
body: <p>This is a real css-challenge, I don't think this is possible:</p>
  
  <p>I've made some white <code>css</code> triangles. and when you hover on a triangle, the white triangle should change in a photo also cropped like a triangle. I've made a jsfiddle for it:</p>

  <p>Any help appreciated</p>
