HOW TO INCLUDE FIGURES in LaTex

- Use the following figure template for one figure:
  
  \begin{figure}[ht]
  \centerline{\psfig{file=<file-directory/file-name>.eps,height=xcm}}
  \caption{\small Some text.}
  \label{fig:xx} 
  \end{figure}

- Use the following template for two or more figures
  WITH DIFFERENT CAPTIONS:

  \begin{figure}[ht]
  \begin{minipage}[t]{.45\textwidth}
  \centerline{\psfig{file=<file-directory/file-name>.eps,height=xcm}}
  \caption{\small Some text.}
  \label{fig:xx} 
  \end{minipage}
  \hfil
  \begin{minipage}[t]{.45\textwidth}
  \centerline{\psfig{file=<file-directory/file-name>.eps,height=xcm}}
  \caption{\small Some text.}
  \label{fig:xx} 
  \end{minipage}
  \end{figure}

- Use the following template for two or more figures 
  WITH THE SAME CAPTION:

  \begin{figure}[ht]
  \begin{center}
  \begin{tabular}{ccc}
  \psfig{file=<file-directory/file1>.eps,height=5cm} & 
  \psfig{file=<file-directory/file2>.eps,height=5cm} & 
  \psfig{file=<file-directory/file3>.eps,height=5cm} & 
  \caption{\small Left: xxx.  Center: xxx.  Right: xxx.}
  \label{fig:xx} 
  \end{figure}
