title: How to get the naturalSize of Vuetify v-img?
body: <p>So I need to get the sizes of an image shown in my page using Vuetify v-img.
  I tried to get the size with <code>naturalHeight</code> and <code>naturalWidth</code> by doing so: </p>
  
  <pre><code>//markup
  &lt;v-img ref="imageShow" @load="getSizes" src"/images/background.jpg"&gt;&lt;/v-img&gt;
  
  //method
  getSizes(){
     console.log(this.$refs.imageShow.naturalHeigth)
  }
  </code></pre>
  
  <p>but it didn't show me the size, it returns undefined.</p>
