!Misplaced \omit.\multispan ->\omit@\multispan

Question

I am trying to show 4 .jpg files in 2x2 format using the following:

\begin{figure}[htb]
\centering
  \begin{tabular}{@{}cccc@{}}
    \includegraphics[scale=0.26]{error1.jpg} 
    \includegraphics[scale=0.26]{afperror1.jpg} \\
    \includegraphics[scale=0.26]{error2.jpg} 
    \includegraphics[scale=0.26]{afperror2.jpg} 
    \multicolumn{4}{c}{\includegraphics[width=.23\textwidth]}
  \end{tabular}
\end{figure}

But I get the following error:

!Misplaced \omit.\multispan ->\omit@\multispan ...c}

which is strange as the image renders fine when viewing the resulting pdf. What is causing this issue?

you forgot the \\ before the \multicolumn and the & between your images. (you have a 4 column table but all your entries are in the first column only) — David Carlisle, Dec 13 '13 at 10:16
