The OPAL experiment at LEP has performed a variety of measurements of
photon-photon and electron-photon scattering at the electron-positron collider
LEP to gain a deeper insight into the structure of the photon and its
interactions. This review presents a summary of these results.Comment: 18 pages with 20 eps files. Invited talk given at the Workshop on
Photon Interactions and the Photon Structure, Lund, Sweden, September 10-13,
1998 to be published in the proceeding
