Figures are not visible inside minipage

Question

I am a novice in Latex. Recently I am trying to use minipage to show some figures. The code I am using is as following:

\begin{figure}[t]

\begin{minipage}[t]{\linewidth}
\centering
\epsfig{file=0.eps, width=7cm}
\caption{Extracting root node coordinates for calculating LEMBR}\label{fig1}
\end{minipage}
\\[1cm]
\begin{minipage}[t]{\linewidth}
\centering
\epsfig{file=1.eps, width=6cm}
\caption{Sending LEMBRs from client sites to Query Site,Calculating GEMBR at Query site and sending them back to client sites parallely}\label{fig2}
\end{minipage}
\\[1cm]
\begin{minipage}[t]{\linewidth}
\centering
\epsfig{file=2.eps, width=4.5cm}
\caption{Partitioning the copy of GEMBR at each client sites}\label{fig3}
\end{minipage}
\\[1cm]
\begin{minipage}[t]{\linewidth}
\centering
\epsfig{file=3.eps, width=6cm}
\caption{Mapping Leaf Level objects at each site on the partitioned GEMBR}\label{fig4}
\end{minipage}

\end{figure}

I am using the above code inside each sections of my paper. But problem is I don't find last 3 figures,it appears to me that those are invisible. What could be the problem? Also, those figures are not found when I am referencing them from my writing,it shows ?? instead.

This is the minimal code which has the same problem, just compile it with some random epsfiles. In this case it doesnt show first four figures and puts ?? in their references.

Answer 1

I don't think TeX can insert page breaks inside figure environments. So, by putting several images inside one figure environment, you may cause some to drop off the foot of the page. The usual arrangement is to have each image inside its own figure environment, along with the appropriate caption and label.

\documentclass{article}
\usepackage{lipsum} %For dummy text
\begin{document}
\lipsum[1-2]
\begin{figure}
\centering
\rule{4cm}{4cm} % Replace with image                                            
\caption{A nice figure}
\label{fig1}
\end{figure}
\lipsum[2]
\begin{figure}
\centering
\rule{4cm}{4cm} % Replace with image
\caption{Another nice figure}
\label{fig2}
\end{figure}
\lipsum[3]
\end{document}

Alternatively, have a look at the subfig package if you want to display several images as part of the same figure.
