I added a png image named MVC Unit 2 Question 1 Graph 1 to the directory, but I am not able to add the image to Latex. I am currently using online Share LaTeX, which I believe is pdflatex.
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{natbib}
\usepackage{graphicx}
\begin{document}
\includegraphics{MVC_Unit_2_Question_1_Graph_1}
\end{document}
\includegraphicsare exactly the same. Pay attention to capitals, spaces vs underscores, extension, etc. – Xavier May 08 '13 at 17:29
