If you're using our default Device Magic Online Database Destination, sketches, signatures & images are stored in Amazon S3 and linked to via a URL.
Just like any other Destination, if you'd rather your images be stored elsewhere, you can deliver these images to alternative online storage facilities like Box, DropBox, your own Amazon S3 account, Google Drive or even SFTP.
Perhaps you want to routinely and easily download them in bulk, or just have the knowledge that these images are under your direct control. To do so, override the default Image Options in Step 3 when configuring the Device Magic Online Database as shown below:
Different storage services have different configuration steps, so we haven't detailed those here but are covered elsewhere on our Help Center.
