Hello,
I am trying to put together a presentation phase for an experiment where the participant views a images for 2 seconds each. I would like images to pop up one by one. I would need these images presented in random order.
I used the following Javascript which worked for the first few items and then began glitching.

var displayTime = 2;
new PeriodicalExecuter(function(){
if($('NextButton'))$('NextButton').click();
},displayTime);

Any help would be appreciated.

Thank you
