When you are logged in your pix-star.com account, whether you are inside the inbox view or the web albums view, you can click on the drop down menu called “bulk action to all pictures” and inside you will find a choice “download all to the computer”.
This will generate a zip file with all your pictures inside that you can download to your computer as a back up.
For web album you need to select 1 web album first, then it’s the same.
