/*document.querySelectorAll('object, embed, applet').forEach(function(e){ document.body.removeChild(e) });*/
document.querySelectorAll('img').forEach(function(e){ e.style.maxWidth='100%'; e.removeAttribute('width'); e.removeAttribute('height'); });
document.querySelectorAll('a[style*="position: absolute"]').forEach(function(e){ e.style.cssText = "" });

document.querySelectorAll('img[src$="\.jpg\.thumb\.jpg"]').forEach(function(e){e.src = e.src.replace('.jpg.thumb.jpg',  '.jpg') });
void 0;
})()

注意，
document.querySelector
和
NodeList.prototype.forEach = Array.prototype.forEach;
NodeList.prototype.filter = Array.prototype.filter;
在有些旧版浏览器里不支持的。
