The \title, \author and \date macros just store their contents in auxiliary macros that is used upon execution of \maketitle. Moreover, \maketitle issues a page break if there is contents preceding it.
As such, I would assume the following would work for you:
% In preamble
\title{My thesis}
\author{me \\
\includegraphics[width=0.5\textwidth]{logo.jpg}}
\date{Thesis\\
for \\
September 2012}
\begin{document}
\maketitle
\clearpage
\thispagestyle{empty}
\begin{center}
\includegraphics[width=.7\textwidth]{basm.png}
\end{center}
\clearpage
% Other document content
\end{document}
You might also consider issuing \pagenumbering{arabic} as part of your "Other document content", to start numbering from page 1 again. However, without a complete MWE showing the structure, it's difficult to assess your use case.
The titlepage environment is also a possibility here. You could use, for example:

\documentclass{report}
\usepackage[demo]{graphicx}% http://ctan.org/pkg/graphicx
\title{My thesis}
\author{Me, me and ME}
\date{\today \\[\bigskipamount] \includegraphics[width=2cm]{me}}
\begin{document}
\begin{titlepage}
\maketitle
\end{titlepage}
\clearpage
\thispagestyle{empty}
\begin{center}
\includegraphics[width=.6\textwidth]{basm}
\end{center}
\clearpage
Here is some more content.
\end{document}
