Random pictures

Question

Hi,

So I am struggling with how to put random pictures in a question.

I've got one question where the participants should just take a look at two of the many pictures that I have uploaded in the "Image and Media Files" section.

P.S. I don't even now where to start, I tried something with those "urns", but simply don't get it at all.

I suggest starting with the manual about Randomization. The case of sidplaying random pictures is explained there including some PHP code (this will be half that bad).

In your case, you will need a random generator that draws 2 codes per interview (this is a setting in the random generator question you create).

When you have your first PHP code and id does not work, feel free to post the code here (please also post the debug information) and ask for details.
