You can put the 5 consecutive images on the same row of the .csv input file. You can also create a blank screen betwen them by simply typing ~ into a stim cell of that row. You can control the presentation time of the blank screen and allow for screen presses in the same way that you used for the images.
Furthermore, you can use the metacommand feature to limit the timing of that entire row. Take a look at this section of the DirectRT manual for information about the metacommand feature: http://www.empirisoft.com/directrt/h...a_commands.htm
