Displaying random item on Data Set

Question

Is there a way to display a random item (row) from a data
set? If not, is it in works for future Spry releases?
I was trying to put a random picture from my gallery on the
front page, but I imagine it would be a feature with which many
other things could be achieved...
Thanks,
Tomas

Hello,
Seems that a small mistake slept in the code above. The
random_row should be casted to an integer value first because the
array of data doesn't have float keys:
function getRandomRecord(){
var data = ds1.getData(true);
var random_row=floor(Math.random()*data.length);
return data[random_row]['image_field'];
where ds1 is the dataset containing the files.
