Call function when image is loaded in VueJS using @load.

In VueJS, there is a way to find out when an image is fully loaded on a web page (when the image request is finished). We achieve this using the @load event that is available in VueJS and works in the following way: 
```
<template>
  <div>
    <img 
      class="img__class"
      src="/photo.jpg"
      @load="onImageLoad"
     />
  </div>
</template>

export default {
  data: {
    isImageLoaded: false,
  },

  methods: {
    onImageLoad() {
      this.isImageLoaded = true
      // optional
      // console.log('Image is loaded')
    }
  }
}
```

This feature will come in handy if we want to render skeleton components while images are loading or if we want to implement lazy loading functionality.
