I have hundreds of figures that I have arranged into 2x2 matrices using the \minipage environment like so:
\begin{figure}[ht] \label{ fig7}
\begin{minipage}[b]{0.5\linewidth}
\includegraphics[width=.5\linewidth]{/home/dnaneet/Research/Dissertation/wigner/Effect_of_domainSize_wavelength/G=0.333/dftdata/L_lambda_max_1wl_profile_0}
\caption{Initial condition}
\end{minipage}
\begin{minipage}[b]{0.5\linewidth}
\includegraphics[width=.5\linewidth]{/home/dnaneet/Research/Dissertation/wigner/Effect_of_domainSize_wavelength/G=0.333/dftdata/L_lambda_max_1wl_profile_Rup}
\caption{Rupture}
\end{minipage}
\begin{minipage}[b]{0.5\linewidth}
\includegraphics[width=.5\linewidth]{/home/dnaneet/Research/Dissertation/wigner/Effect_of_domainSize_wavelength/G=0.333/dftdata/L_lambda_max_1wl_dft_0_corner}
\caption{DFT, Initial condition}
\end{minipage}
\hfill
\begin{minipage}[b]{0.5\linewidth}
\includegraphics[width=.5\linewidth]{/home/dnaneet/Research/Dissertation/wigner/Effect_of_domainSize_wavelength/G=0.333/dftdata/L_lambda_max_1wl_dft_corner_Rup}
\caption{DFT, rupture}
\end{minipage}
\end{figure}
I find that with this kind of an arrangement I have lots of white space after the figures. How should I ensure that I use all the "page real-estate" for my figures without too much white space?
I am really sorry that I can't seem to explain my problem any better.

How to avoid spilling of images into following page?
As per the comments, when I use \includegraphics[width=x\linewidth] with x>0.5, my images spill into the following page. I would like my table and image to be in the same page and have the images leave little white space:
Images moving to following page:

I would like this with lesser white space:

\pagebreakbefore the table will force a page break and cause the table and figure to show up on the same page, but at the possible expense of a lot of empty whitespace on the preceding page. – A.Ellett Aug 05 '13 at 18:01\centeringinside thetableenvironment? – A.Ellett Aug 05 '13 at 18:13
