The Manage Hosting area is broken up into three sections:
You upload, create and manage ImageSets in this section. An ImageSet is a set of assets (JPG or PNG images, MP4 video, YouTube or Vimeo URLs, and 360º SpinSets) that you assign to a particular product.
This is where you can set up features such as automatic generation of thumbnails (including Trigger images), and your FTP settings so we know where to deliver the trigger images. Additional functionality is available based on your subscription in the Plugin Store such as Swatch Support and Inventory Awareness.
