dimensionando elementos con jquery

[mayid]

Yo tengo esto:

img.resized{cursor:pointer; width: 780px}

$("img").each(function(i){

//only process the foreign ones
IMGsrc = $(this).attr("src");
if (IMGsrc.search("http") != -1)
{

// check the width of the image
if ($(this).width() > 780) {

$(this).addClass("resized"); // apply resized class

$(this).click(function(){
location.href = this.getAttribute("src");
});
}

}
});
