slide and collapse working together

slide and collapse working together

I have a page with 4 rows and 2 cols, in each of this rows is a bootstrap accordion and an image which is in the other column.
When the header is clicked the accordion opens(bootstrap collapse) and a hidden div with images is shown under the image already visible on the page (slide jquery).

So with one click 2 divs open(accordion body+hidden div), this works for all 4 accordions when I use different ids for the accordions, but they stay open. I like to have them close if another header is clicked.

This code doesn't work
 
$('.accordion-heading').click(function (){
    $('.slidepic').each(function (index) {
        if ($(this).attr("id") == slides) {
            $(this).slideDown(200);
        } else {
            $(this).slideUp(200);
        }
    });
});

There is a fiddle here: http://jsfiddle.net/SUpmn/5/
Could somebody shares his light on this?
Thx
