Millisecond Forums

We have set of 20 images. With the help of item property (and the noreplace function) these 20 images are used for the picture element that will serve as a target stimulus. There will be 5 trials in one block. So from the set of 20 images 5 is chosen randomly and presented to the participant. 

In the next block these 5 randomly chosen images need to be shown again. The question is how to record which 5 images were picked up in the first block so exactly these 5 can be used in the second block. What function (if any) can help me to achieve this. Will be very grateful for any help.

Best wishes
