I'm new to writing Gulp plugins, be gentle. If there's anything you find wrong with this, please help.

Known Issues

• Using an image file extension in a CSS class will result in a match and won't delete the image. The same happens using dot notation in JavaScript files

  div.jpg { background-image: url('images/some-image.jpg'); }
  
  ---
  
  if (myObj.file.images.jpg) {
  //...
  }

• If multiple image files exist in subfolders that are under the root directory and the name is referenced in the source file. It won't delete any of the named files that match.

  images/filename.jpg
  images/subfolder/filename.jpg
  
  ...
  
  <img src="images/subfolder/filename.jpg" alt="Some great file">
