Placekitten — Placeholder images of kittens

A cute kittenA cute kitten

In the spirit of, Mark James has created placekitten, a service that provides pictures of kittens that you can use as placeholder images when designing websites.

But that's not the only use for this service. Lee Semel has created a jQuery plugin, jquery-placekitten to replace all images on the current page with images from placekitten, and Hacker News user sisk created this bookmarklet that you can paste into your URL bar and will replace all images on the current page.

javascript:(function(){var a=document.getElementsByTagName('img'),i=a.length;while(b=a[--i]){b.setAttribute('src',''+b.width+'/'+b.height);}})();

I love you, Internets.
