On the portal, you can select from your uploaded thumbnails and request the original size versions, which will be uploaded to the server under your account.
At the image preview page, select the image you want the camera to upload the original image by checking the box, then select Request Original action and click Go. You can check more than one thumbnail image before requesting the original resolution photo(s).
If Real Time mode is ON, the camera will upload the original image immediately. If Real Time mode is OFF, the camera will upload the original image the next time it connects to the server, after sending a photo (motion-triggered, time-lapse, or even) or scheduled status report.
After the original image has been uploaded, you will see an Original icon above the right corner of the thumbnail image.
