Centering a table of images

Question

I'm trying to center a table of images; 2 images per table row. Right now the code I have is ugly, and doesn't center on the document. I've tried using \begin{center} and \centering without any luck.

Also The way I created it, it currently creates a new table for every line. It's not ideal, but it the best I came up with so far. This is because I need to alternate text and images (for a caption effect, when I try to use the \caption I can't get the 2 column effect or the caption centers without the image and it's ugly)

Is there a way I can accomplish this considering there are about 100 images?

\begin{document}
stuff
stuff
stuff
\begin{center}
stuff that centers
stuff that centers
\figureLoop{pic(}{).jpg}     %Doesn't center :(
stuff that centers
\end{center}
\end{document}

The first parameter is the front half of file name (separated by a number that increases in the loop) and the 2nd part is the rest of the file name.

\newcommand{\figureLoop}[2]
  {   
  % Condition to loop; intitialized to true.
  \bool_set_true:N \runWhileLoop        
  % Place holders
  \int_zero:N \counter
\tmp=0
\Counter = \counter   

  % Run while condition is true
  \bool_while_do:Nn {\runWhileLoop}
  { 
        % Increment the counter   
    \int_incr:N \counter
    \Counter = \counter   
        % Create file name from the counter
    \edef\fileName{#1\int_use:N\counter#2}
        % Increment for the 2nd column
    \int_incr:N \counter
        % Define the 2nd column figures/number
    \edef\filename{#1\int_use:N\counter#2}      
        % Check if the file exists
    \file_if_exist:nTF {\fileName}
    {
            % Check to see if the 2nd column file exists/is necessary
        \file_if_exist:nTF {\filename}
        {
                \begin{table}[!htbp] 
                \begin{tabular}{c c}
                    \includegraphics[width=3.5cm]{\fileName} & \includegraphics[width=3.5cm]{\filename} \\
                    Image \number\Counter & Image \number\counter \\
                \end{tabular}
                \end{table}
        }{
                % If there's an odd number of photos
                \begin{table}[!htbp] 
                \begin{tabular}{c}
                    \includegraphics[width=3.5cm]{\fileName} \\
                    Image \number\Counter \\
                \end{tabular}
                \end{table}
        }   

        \advance\tmp by 1
        \ifnum\tmp=4
            \newpage
            \tmp=0
        \fi
    }{
        % there is no file with the given name
        % break the loop
        \bool_set_false:N \runWhileLoop
    }
  }
}

And this is what I currently get. This is the idea I want but centered completely. Any advice would be helpful, but I'd prefer something that has as little modification as possible.

Please always post complete documents not fragments but...

Since you are not using caption and don't want the things to float just don't use

 \begin{table}

 \end{table}

then the tabular will centre. If you do use table you need \centering inside the table as floats reset the paragraph parameters
