  We report on imaging of the nonuniform superconducting states in a Pb thin
film bridge on top of a ferromagnetic BaFe_{12}O_{19} single crystal with a
single straight domain wall along the center of the bridge by low-temperature
scanning laser microscopy. We have visualized domain wall superconductivity
(DWS) close to the critical temperature of Pb, when the Pb film above the
domain wall acts as a superconducting path for the current. The evolution of
the DWS signal with temperature and the external-field-driven transition from
DWS to reverse domain superconductivity was visualized.
