You can't upload drawing to RMD, all drawings are created with the RMD online drawing tools.
To get started all you need to do is click "Draw" at the top of your screen. The next screen that comes up will guide you through all the easy steps that you need to know. Once you've picked your preferred drawing tool and canvas size, you will be taken to the next screen where you will then draw your picture. Once your picture is finished you will click "Save to website", then you will choose a title and agree to the terms of service, then your picture will be visible in your gallery. I only use Javadraw so it's probably different for the other drawing tools. Anyway, it's as simple as that. Someone else will most likely come along and explain it better than I can.
