I am using sharelatex.com to draft a manuscript for jjap/ apex. Using the jjap.cls file for template. I've use
\usepackage{graphics}
Figures syntax:
\begin{figure}[ht]
\centering
\includegraphics[width=2cm,height=5cm]{peak.jpg}
\caption{\label{figure_2}vvv}
\end{figure}
However, the figures does not show up after compiled and error in output.pdf.
\labelshould be placed outside of the caption (see https://tex.stackexchange.com/a/32326/). More on-topic: did you upload the image file? Is the original filename also in lower case? – Marijn Jul 03 '18 at 15:00\usepackage{graphics}by\usepackage{graphicx}(with anx), see https://tex.stackexchange.com/questions/23075/packages-graphics-vs-graphicx. – Marijn Jul 03 '18 at 15:42
