[Tugindia] Figure insertion - Removal of blank space

[G.Abhilash]

Dear LaTeX users,

I have used the following commands to place a figure given in .pdf format
(figure.pdf).

 \usepackage{graphicx} % (in the preamble)
 .
 .
 \begin{document}
 .
 .
 \begin{figure}[ht]
 \includegraphics[width=6cm, height=5cm]{figure.pdf}
 \centering \caption{....} \label{...}
 \end{figure}
 .
 .
 \end{document}

And compiled this file using the command 'pdflatex'. Eventhough the figure
gets placed, there is lot of blank space left surrounding the figure;
particularly, between the lower end of the figure and the caption, and
above the figure.

Is there any way to remove this unnecessary blank space? Please help.
