Eclipse lights curves at U, B and R are used to reconstruct images of the accretion disc in the eclipsing cataclysmic binary RW Tri. The disc is shown to be optically thick, with temperatures that range from 10 000 K at the outer edge to 40 000 K near the centre. The radial temperature profile is consistent with the expected |T∝ R-3/4| law for steady-state accretion. The angular size of the disc indicates a distance of 500 pc. The mass accretion rate is |Ṁ=10-7.9± 0.4M_\,yr⁻¹|.
