Urgent: Latex question

Hi,

I have prepared a latex document in which I inserted a figure as..

\begin{figure}[ht]
\centerline{\psfig{file=figs/test.eps,height=12cm}}
\caption{\small Test.} \label{fig:test}
\end{figure}

But when I compile this, I get the figure, but I also get a small icon like figure on the top left corner of the page.
How can I fix this?

Also how do I cite a picture. I am doing in the following way but I am getting error "! Undefined control sequence."

\begin{figure}[ht]
\centerline{\psfig{file=figs/test.eps,height=8cm}}
\caption{\small test~\cite{test}.}
\label{fig:tes}
\end{figure}

I need this urgently I can increase the point if you give me a good solution

Thanks
venkat.
