It is my very very first time using LaTeX and I only need this program for preparing a homework which must include some graphics. For that I've been reading what to do for inserting an image but still not being able to add one, I seek for any kind of help. Would be very nice if you can explain this problem below and give me an advice.
! LaTeX Error: Can be used only in preamble.See the LaTeX manual or LaTeX Companion for explanation.Type H <return> for immediate help.... \usepackage
What I typed is this:
\documentclass[10pt]{article}
\begin{document}
\usepackage{graphics}
\includegraphics[scale=1]{ad.png}
\end{document}
Thank you in advance.
\usepackage{...}has to go before\begin{document}(the part which is known as the preamble). – sodd Feb 22 '16 at 22:11
