Well, you can write something like this… …which gives the browser permission to show content before the image has finished the loadinganddecoding process. That’s a pretty neat trick, if you ask me. From JavaScript to paper: a linocut adventure I absolutely adore blog posts like this one...
By setting the decoding attribute to async, you are suggesting that the decoding of the image can be deferred. By setting it to auto or omitting the attribute, you are letting the browser decide fully on when the decoding should be carried out. Note that this attribute acts as a hint only...

直接翻译过来就是 —— 页端可以通过 Image.decoding 属性来控制图片解码的行为,sync 会强制同步解码,图片会和其它内容同时显示,async 则强制异步解码,可能会造成图片和其它内容不同时显示,默认值 auto 则让浏览器自己来决定。 上述描述的“和其它内容同时显示或者不同时显示”究竟是什么意思呢?这个跟浏览器合成器的...
