The following format should be used when referencing online images taken from a web site.

As yet, there is no fixed standard applied to citing electronic sources – the key is consistency. If you apply a consistent style throughout your work, your reader will be able to understand the information and trace the sources that you have used
If no obvious orginater is mentioned, try and identify the person or organisation that is responsible for the website i.e. “BBC”, and treat as a corporate author.
Remember anyone can post an image/chart or table on the web and they might not be the Originator or have permission to post the video. It is always best to ask the same questions as you do in respect of web pages Who, What, Where, When and Why. If you can't satisfactorily answer these questions then it is probably best to use a different resource in your work. If you are looking image for your work look for a creative commons licence. E.g. Wikimedia Commons or other copyright statement
If a website/ebook/ejournal uses an image, chart or table that comes from an other source (this is called secondary referencing) and should be cited in your work as such see the secondary refrencing section for futher details.
