I’ve made a plug-in which allows synegry users to add a QR tag with a shortcode.

This works as follows

[[SDS_QRCODE size=”200″  alt=”medialab qrcode” code=”http://medialab.st-andrews.ac.uk” align=”left” cssclass=””]]

the parameters used are:

size – in pixels – (optional) default 150px
alt – alt tag for QR image (optional) default ‘qrtag’
code – web address or text code for QR tag to display
align – image alignment – (optional)
cssclass – CSS class – (optional)

the above shortcode would output:

[SDS_QRCODE size=”200″  alt=”medialab qrcode” code=”http://medialab.st-andrews.ac.uk” align=”left” cssclass=””]
