Change image size

Use the scale=0.5 option in the \includegraphics command to shrink the image to 50% of its original size. That is, \includegraphics[width=50mm,scale=0.5]{method.eps}. You can use a different percentage if needed.

I usually just do \includegraphics[width=0.7\columnwidth]{figure}, where 0.7 is the fraction of the column width.

This is useful for IEEE double column papers.

\includegraphics[scale=0.25] {name.jpg}

This works well. scale=0.25 is to shrink the image to 0.25 but can use any ratio.
