rxbag (Boxturtle) has this functionality for individual frames. From the
wiki <http://www.ros.org/wiki/rxbag_plugins>:
*Right-clicking on the image opens a context menu which allows you to resize
the window to the original resolution, or save the image to a .png file.*
rxbag (C-turtle) will allow exporting multiple frames.
