title: Coldfusion 7: Saving Base64 Image to Server
body: <p>A client needs us to generate a lot of dynamic QR codes for a project their doing. I think the end up being some hybrid between Name tags and event markers. In any case I've generated the QR just fine in JavaScript. Between JS and ColdFusion I'm even able to generate hundreds of dynamic QR codes in a second. The problem is now they're just sitting in the temporary memory of what ever client machine made them. I can send them as a form post in a 'text' input so I could begin something like a file upload, but that's where I stop having ideas.</p>
  
  <p>How do I have these Base64 blob strings as PNGs on my server using ColdFusion?</p>
  
  <p>I have CF7 so I don't have access to cfImage that I'm aware of. </p>
