The DQRS (DynamicQRSaver) generates a dynamic QR-Code. This QR-Code / the URL gets saved in the WordPress-Database and can be changed later on. 
Simply edit the QR-Code URL in the Backend-Tab.

Dynamic QR Code URL Saver

Idea is great because so many dead liks are the and some qr codes will e printed as well.

I red that pretty links offer this but can't find this option there.
I would love to have an export there and best case directly from post editor ;)

I would like to believe the best ;)

Generates a dynamic QR-Code, which can be saved and edited later, even if the QR Code was printed. Very easy to install and use. Share smartly!

This plugin lets you specify a header image for each post, page, custom post type or archive page individually, from your default headers and custom headers.
It adds a meta box in the post edit screens with the header selection and a settings field in the edit profile and each taxonomy edit screen. 
If no specific header is specified for a post it will fall back to the default selection. 
There is no change of template files necessary as this plugin hooks in the existing WordPress API to unfold its magic.
Thanks to Erik T. for the idea to this plugin!
