I am trying to place two images in top of two columns in a columns environment, in a beamer presentation.
The first column consists of one image on top and a enumeration list bellow the image.
The thing is that I want the column to start at the top of the frame, which isn't happening in my case. My code is
\documentclass[slidestop,compress,mathserif,11pt,xcolor=dvipsnames]{beamer}
\usepackage{beamerthemebars}
\usepackage[bars]{beamerthemetree}
\usepackage{multicol}
\setbeamercovered{higly dynamic}
\usetheme{Ilmenau} % Beamer theme v 3.0
\useoutertheme[subsection=true]{smoothbars}%Beamer Outer Theme-circles on top
\usefonttheme{serif}
\useinnertheme{circles}
\begin{document}
\section{Εισαγωγή}
\begin{frame}
\frametitle{Nuclear Propulsion}
\begin{columns}
\begin{column}{0.48\textwidth}
\begin{figure}[t]
\includegraphics[width=\textwidth]{AtomicSubmarine}%\vspace{0.5cm}
\end{figure}
\tiny{\begin{enumerate}
\item Item1$\rightarrow$ Conclusdion
\item Item2$\rightarrow$ Conclusdion
\item Item3$\rightarrow$ Conclusdion
\item Item4$\rightarrow$ Conclusdion
\item Item5$\rightarrow$ Conclusdion
\item Item6$\rightarrow$ Conclusdion
\end{enumerate}}
%\begin{minipage}[t]{0.99\textwidth}
%\includegraphics[width=\textwidth]{AtomicSubmarine}
%\end{minipage}
\end{column}\hfill
\begin{column}{0.48\textwidth}
%\begin{minipage}[b]{0.99\textwidth}
\begin{figure}[t]
\includegraphics[width=0.9\textwidth]{SubmarineSnorkel}
\end{figure}
%\end{minipage}
\end{column}
\end{columns}
%\begin{minipage}[b]{0.5\textwidth}
%\includegraphics[width=\textwidth]{SubmarineSnorkel}
%\end{minipage}
\end{frame}
\end{document}
The output of this code is

It is clear that a few lines upper would be ideal, as the real presentation frame, states!

I've tried to remove the figure environment, to use minipage but the right image is aligned with the list, resulting in a very bad format. One solution is to remove the frametitle but I'm afraid I need it...
Another idea is to use \vspace{-1cm} but I am not sure if this is the optimum solution...
Any ideas on that?
