  This method requires authentication with 'write' permission.
  <br>
  The tagId parameter must be the full tag id. Methods such as photos.getInfo will return the full tag id as the
  "tagId" parameter; other methods, such as addTags, will return the full tag id in the "fullTagId" parameter. If
  this method does not seem to work, make sure you are passing the correct tag id.
  
  @param tagId tag to remove from the photo. This parameter should contain the full tag id.
  @return response object indicating the result of the requested operation.
  @throws JinxException if the parameter is null or empty, or if there are any errors.
