We have performed RIJHK_S imaging of the field around the z=2.67 quasar Q0836+113, which presents several metal line and a damped Lyα absorption systems in its spectrum. The images reveal the existence of a red K_S=18.9 object ≃ 11 " from the quasar. On the basis of the empirical relationships between absorption radius and luminosity we conclude that this object may be the CIV absorber at z=1.82. This could be the first detection of a high redshift galaxy causing high-ionisation absorption. After carefully subtracting the QSO, we do not detect, up to a 3σ limiting magnitude for extended objects of K_S=20.8, the damped Lyα absorber apparently detected as a Lyα emitter at z=2.47. This imposes an upper limit on its Hα emission comparable to the results obtained spectroscopically by Hu et al. (1993ApJ...419L..13H). It is also suggested, that object "SW" from Wolfe et al. (1992ApJ...385..151W) could be the galaxy responsible for the claimed MgII absorption at z=0.37.
