The latest analysis efforts in reverberation mapping are beginning to allowreconstruction of echo images (or velocity-delay maps) that encode informationabout the structure and kinematics of the broad line region (BLR) in activegalactic nuclei (AGNs). Such maps can constrain sophisticated physical modelsfor the BLR. The physical picture of the BLR is often theorized to be aphotoionized wind launched from the AGN accretion disk. Previously we showedthat the line-driven disk wind solution found in an earlier simulation by Progaand Kallman is virialized over a large distance from the disk. This findingimplies that, according to this model, black hole masses can be reliablyestimated through reverberation mapping techniques. However, predictions ofecho images expected from line-driven disk winds are not available. Here, afterpresenting the necessary radiative transfer methodology, we carry out the firstcalculations of such predictions. We find that the echo images are quitesimilar to other virialized BLR models such as randomly orbiting clouds andthin Keplerian disks. We conduct a parameter survey exploring how echo images,line profiles, and transfer functions depend on both the inclination angle andthe line opacity. We find that the line profiles are almost always singlepeaked, while transfer functions tend to have tails extending to large timedelays. The outflow, despite being primarily equatorially directed, causes anappreciable blue-shifted excess on both the echo image and line profile whenseen from lower inclinations ($i \lesssim 45^\circ$). This effect may beobservable in low ionization lines such as $\rm{H}\beta$.
