Add an image to contact entity and in the SSRS report

Hello Experts,

We have a requirment in which we have to produce the QR code of each contact and include it in the SSRS report

We already found how to generate QR code as image from

chart.googleapis.com/chart;cht=qr&chl=Hello%20world

So what is the best way to save this image for each contact, can we use existing image field or create a new web resource and populate it with image or create new entity to store the contacts and QR code?

Also we need to include this QR code image in the SSRS report

Please provide your suggestions

Thanks in Advance.
