Base 64 Image - upload and save using wappler?

Stumped! Been at this for hours!

Hi All, I am using webcam.js to take an image capture. I convert the javascript variable which it produces (base64) into a appconnect variable.

I now have the form for uploading to the server, an input field which contains the base64 string.
My question is how do I go about saving the variable to the server as a *.jpg file using file upload, then save name that to a table.

Any help would be greatly appreciated.
