Cleanly replace missing images in web page

imageReplace

/*
 The below img error snippet will instantly hide any broken image placeholders
 although it appears there's extra steps happening here (hidding and unhiding),
 The reason is that the split second delay of reloading a new placeholder image
 can cause the ugly missing image placeholder to flash if we don't hide it instantly on err.

$("img").error(function () {
  $(this).css({visibility:"hidden"});
  $(this).attr({src:'/images/theme/no_logo_placeholder.png'});
  $(this).css({visibility:"visible"});
});
