Switching an image using jQuery

Question

Is there a better, more jQuery-ish way of handling this image substitution?

var image = $(obj).children("img");
if ($(image).attr("src") == "Images/TreeCollapse.gif")
   $(image).attr("src", "Images/TreeExpand.gif");
else
   $(image).attr("src", "Images/TreeCollapse.gif");

Answer 1

Why set a variable when it isn't needed?

$(obj).children("img").toggle(
  function(){ $(this).attr("src", "Images/TreeExpand.gif"); },
  function(){ $(this).attr("src", "Images/TreeCollapse.gif"); }
);
