Graphics, Figures & Tables ⇒ Extra space between image and caption

[Fordprefect]

\begin{figure}[htb]
\centering
\includegraphics[width = 4in]{Figure2b}
\caption{\label{Fig2} dummy caption.}
\end{figure}

This is the code I am using to layout my images in a paper. 5/6 are fine, but one of them always compiles with extra space (probably 15 lines) between the figure and the caption. I have tried everything within my knowledge base to correct this, but that is pretty limited. Any suggestions?

I assume the extra space is in the image. By putting the image inside a \fbox one can verify this:

Code: Select all

\fbox{\includegraphics[width=4in]{Figure2b}}
