Add QR code to Tumblr Posts

It’s super simple to add a QR code to each Tumblr post. Just add this to anywhere between {block:posts} in your custom template.

{block:posts}
<img src="http://chart.apis.google.com/chart?cht=qr&chs=116x116&chl={ShortURL}"/>
{/block:posts}

Here is an Example on my tumblr.
