Selecting picture randomly

[hehe]

Hello, I attached a experiment in direcrt.
In this experiment, it is possible that any photo with certain no. may be selected by a subject. I used the open-end respose function, but only the no. in the photo was showed, I want to show a photo with certain no.
can you help me?
Best Regards.

Mmm, I can see where you are going with this (nice idea) but I think what you are looking for is most easily accomplished using skips something like this:

C:\DirectRT\samples\3 ordering trials\skipping.csv

Take a look at that sample (and skipping in the users guide) and see if that helps.
