If you would simply like to record the number of clicks in the data, you can use JavaScript to detect clicks on an element and increment the value of a text or numeric input.
For example, if using the latest LS version with the default template, setting up your survey to use JavaScript and adding the following script to to the source of a numeric question will increment its value every time an image in the question text is clicked.

$(document).ready(function(){
$('#question{QID} .question-text img').on('click', function(i) {
$('#question{QID} input[type="text"]:first').val(Number($('#question{QID} input[type="text"]:first').val())+1);
});
});
</script>
