Center image vertically and horizontally, CSS and jQuery a.k.a. image lightbox

In my opinion you should use libraries rather than role your own solution, but I came across this Stackoverflow question and couldn’t resist rolling my own lightweight, lightbox implementation. Here is a link and to my jsFiddle where the magic happens. Check out the results:

HTML5 Canvas API, Paper.js, Raphael.js, Processing.js: Performance, Benchmarks and a New Trick
