Basically, if it is an image, <object> is equivalent to <img> if it is a nested browsing context, <object> is equivalent to <iframe> otherwise, <object> is equivalent to <embed> (except that <object> has a richer fallback mechanism than <img>, <embed> doesn't have one at all) Though, now that HTML5 introduces <video> and <audio>, I wonder if <object> couldn't be equivalent to those when type of the resource is some video or sound... -- Thomas Broyer
