Question

I have a div with the id ring-preview, it has a unspecifed number of img elements with the class stone-preview inside it.

I would like to iterate over each of these child images and call:

$(this).rotate(ring.stones[i].stone_rotation);

Where this refers the img element and i refers to its position within the div.

How can I do that?

You’re looking for the .each() method.
For example:

$('.ring-preview').children('img').each(function(i) { 
    $(this).rotate(ring.stones[i].stone_rotation);
});

If the <img> elements aren’t direct children, you’ll need to call .find instead of .children.
