To find count of images in div you can use descendant selector (“ancestor descendant”)to find descendant of type img in the div having id div2

Live Demo

$("#div2 img").length;

Selects all elements that are descendants of a given ancestor, reference.

When you use this $( "#div2" ) it means - element with ID="div2". and as you know there could be only 1 such element because id is unique. For getting all the divs use $( "div" ) for getting all the elements wit div2 class use $( ".div2" )

I believe you're looking for

var n = $( "#div2 img" ).length;
