     With the aim of measuring time delays for a sample of gravitationally lensed QSOs we are conducting a long-term photometric monitoring project at the Nordic Optical Telescope (NOT). We present photometric light curves with preliminary time delays and deep high-resolution images obtained using the MCS image deconvolution algorithm.
