We review recent advances in stellar surface imaging techniques brought
about by the advent of signal enhancement methods that utilize the
profiles of hundreds of photospheric absorption lines
observed simultaneously. Highlights from the recent use of these
techniques include evidence for strong azimuthal field components in the
photospheres of active stars, and the first successful use of starspot
tracking to measure stellar surface differential rotation. We discuss
future prospects for the use of these techniques in mapping stellar
surface flows and magnetic-field configurations in a wide variety of
stellar types.
