I am preparing slides for a presentation and would like to add some figures, but whenever I try to include graphics, I get the following result:
That is, instead of the image that is supposed to be included, a box with the relative path to the image is displayed. The same error also results when I move the image to the same directory as the LaTex file.

\includegraphicscommand is erroneous or the image is not there. Try without the file extension – percusse Aug 31 '15 at 21:40draftoption loaded anywhere? Perhaps in\documentclass[...,draft,...]{beamer}, or with\usepackage[draft]{includegraphics}? – Werner Aug 31 '15 at 21:49\includegraphics– Werner Aug 31 '15 at 21:52
