Can I select a new design when editing the code?

Each Visual QR code is made up of a base image, onto which a QR code position and a QR Code destination are integrated. 

While you can always edit the QR Code’s destination in any QR Code design project, if you want to use a new image with the same QR Code, you will need to create a new QR code design. The other side to this is that, creating a new QR code is really easy and simple to do by using Visualead's Visual QR code generator and shouldn’t take you more than a minute.
