Secret thumbnails let you replace your content’s thumbnail image with a generic placeholder so that the actual content remains a surprise until it's printed.
Normally, the content of print products can be previewed on each creator’s FANBOX Print page or on multi-function printers and copy machines. However, when using this feature, the content will remain hidden.
You can enable secret thumbnails when registering your content. Use them if you want to avoid spoilers, or if you'd like to deliver a special message that can only be seen by those who print it.
