Those modules are optional.  How do you write your links in the org
file?  To be included in LaTeX export with includegraphics, the
description part of the link should be empty.  e.g.

  [[/path/to/image]]

This creates an inline image in the final pdf.  You can add a caption by
adding a caption line like this:

  #+CAPTION: Some caption

If you add a caption, then the image is enclosed in a floating
environment (figure in this case).

For details see the manual: (info "(org) Images in LaTeX export")
