jQuery: Set Image Height Based on Width for .sj_post_pic Element

To get the width of the '.sj_post_pic' element and set its height using jQuery, you can use the following code:

$(window).on('load resize', function () {
    var postPicWidth = $('.sj_post_pic').width();
    $('.sj_post_pic').css('height', postPicWidth);
});

This code will execute when the window is loaded or resized. It will get the width of the '.sj_post_pic' element using the width() function and then set its height equal to its width using the css() function.
