What Is a Mystery Pack?
What a mystery pack means in a digital archive catalog and how it differs from a pack with preview images.
Quick answer
A mystery pack is a release whose source does not provide a usable public preview image. The pack can still have known metadata such as file count and total size, but its contents are not visually previewed before unlocking.
Why would a pack have no preview?
Some source folders contain no image files suitable for a preview. Others may contain images that cannot be fetched reliably without exposing the underlying delivery link. In those cases, a neutral placeholder is clearer than pretending a preview exists.
A mystery label should describe preview availability, not make claims about the quality or type of the underlying files.
What information can still be shown?
File count, total size, release date, and unlock cost can still be useful even when no image is available. Those values help explain the scale of the pack without revealing the protected delivery URL.
How mystery packs should appear in a catalog
They work best when mixed naturally among preview-backed releases rather than dominating the page. If a pack actually has working photos, it should remain an image-backed release and should not show mystery artwork in place of a failed secondary preview.
