The analysis of the OGLE-I data using the standard profile-fitting software yielded a large set of new variable stars. However, due to the severe crowding of the images many variables may have been missed. Therefore, we decided to reanalyze these data by means of the image subtraction method. Our main goal was the detection of new variables. In addition, we intend to extend the time-base of the observations for the variables found in the course of the OGLE-II project (Udalski et al. 1997). We present the preliminary results of our study.
