  // name. This is necessary so that
  // - the Javascript that process this page and inserts code to your textarea

  //   editor)
  // - the code that processes the img_assist filter tags can work with standard
  //   sizes and custom sizes in the same way.
  // The WYSIWYG placeholder, however, is the most important reason to keep the
  // img_assist tags this way. This way users can even resize images in the
  // editor, and if they aren't allow to create custom sizes the filter will
  // pick the existing derivative that is closest to the size of the WYSIWYG
  // placeholder. For users not familiar with pixel sizes or names like
  // 'thumbnail' and 'preview', this is a nice visual way to size images.
  // The size selection dropdown could even be hidden using the stylesheet,
  // making the insertion of images even more of a visual process. And for
  // administrators and those with the proper permissions, images don't have to
  // snap to the nearest standard size. You can create any arbitrary size you
