P4Thumb User Guide (2020.1)
About the P4Thumb Guide
P4Thumb, the Helix Thumbnail Generator, creates thumbnails of graphic files managed by Helix Core and stores them in the Helix Core server, also called the Helix server. A thumbnail is a 160x160 pixel PNG representation of the image. P4V, the Helix Visual Client, displays the thumbnails in the right pane when you choose View > Show Files As > (Large/Medium/Small) Thumbnail.
