Well, here an idea
1. For each face create a group (all groups get the same "group randomization name")
2. In each group create a question of type equation where you generate a random number between 5 and 9
E.g.: {if(is_empty(G1rand),rand(5,9),G1rand)}
3. Create a question of type list(radio) or "Yes/No" with this question text (source code mode) and adapted to names, explanation and random number.
Code:
<div id="d1"><img alt="" src="/limesurvey/upload/surveys/123456/images/Face001.jpg" /></div>
<div id="d2">Alice has lost her job</div>
<div id="d3">Alice gets ${G1rand}, you get ${10-G1rand}
<p> </p>
Do you accept or reject?</div>
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$('#ls-button-submit').hide();
$("#d2").hide();
$("#d3").hide();
$(".answer-container").hide();
setTimeout(function () {
$('#d1').hide();
$('#d2').show();
}, 4500);
setTimeout(function () {
$('#d2').hide();
$('#d3').show();
$(".answer-container").show();
$('#ls-button-submit').show();
}, 8000);
});
</script>
As you see the first div, the image, is shown for 4,5 seconds, everything else is hidden.
The the image is hidden and the second div, the explanation ("Alice lost her job"), is shown for 3,5 seconds.
And at last this explanation is hidden and the third div, the question, and the answer container and the next button are shown.
And the result you may display in a next question of type "text display".
Nevertheless, you should show us a bit more than the article.
