You can download your photos out of Sonlet using the Image Takeout button, located on your Home screen. 

The number of downloads you can make each billing period will depend on your Plan. Your images will be emailed to you in the form of a zip drive.  Depending on the size of your inventory, it could take a few hours.  Your download link will be valid for 24 hours.

Click Image Takeout, and it will tell you how many unsold inventory you have available to be downloaded.  It will tell you how many times you have downloaded your inventory in the last 30 days. It will also indicate the email address we have on file for the zip drive to be sent to. Click Download Images to begin the download.

Be aware that the zip drive will contain the pictures under their original file names, not how they've been organized into Sonlet.
