My attempt is to put multiple photos in a page, which are not related to each other. However, they overlap and making page look ugly. Is there a way to separate these photos? the document class can be downloaded from here
MWE :
\documentclass{sig-alternate}
\usepackage{listings}
\usepackage{amsmath,graphicx}
\usepackage[bottom]{footmisc}
\usepackage{multirow}
\usepackage{makecell}
\usepackage{epstopdf}
\begin{document}
\begin{figure}
\begin{center}
\includegraphics[scale=.35]{plot1.eps}
\end{center}
\end{figure}
%some text goes here and then...
\begin{figure}
\begin{center}
\includegraphics[scale=.45]{plot2.eps}
\end{center}
\end{figure}
\end{document}

\documentclass{...}and ending with\end{document}. – Astrinus Apr 22 '15 at 14:36article? If so, you don't need to include your special document class in the example! On the other hand, if the problem only shows up with\documentclass{sig-alternate}, that's a big hint about where to start looking for the cause. – Tyler Apr 22 '15 at 15:03\includegraphics{example-image}should work on a reasonably up to date tex distribution. If you can only make the problem with your images, the problem is your images, not tex, if you can make a generic example, post it... – David Carlisle Apr 22 '15 at 15:24\includegraphics{example-image}latex will include an image that is included for this purpose in all modern tex distributions, which means that anyone trying your example will see the same output as you. But if you can not generate the problem using that image, that is useful information, pointing to my initial guess that there is a problem with your eps files. – David Carlisle Apr 22 '15 at 15:43
