Where you include any images in your essay, thesis or work, you can describe them as figures. You will need to include them in reference. Figures need to be numbered e.g. Figure 1. or Fig.1 or Figs. 1,2,3. and captioned (described), place caption directly under the image. Number all Figures in the order they first appear in the text. Figures must be referred to in the main body of the text.
