I wouldn't recommend a 'GET' request, POST fits the use case better. No need to expose the entire image in the URL, as that gets written to the logs. I'd hate to have logs filled up with images. DB table should be fine, as the toDataURL gets the image as base64, If you need to get the file out, you just need to base64 decode that to a png.
