ScreenShot Hack (also spelled ScreenShotHack; some versions are apparently just named ScreenShot) is a utility which makes screen shots on a Palm OS device
Some or all versions make use of an API (or something like that) supplied by an application called "Hack Master". ScreenShot Hack is one of a whole family of "Hack" programs.
ScreenShot Hack stores captured images in a file named ScreenShotDB.pdb, which is presumably the format supported by third-party utilities that support ScreenShot Hack format. This file is presumably a type of Palm OS Database file, perhaps similar to the TealPaint or Palm Database ImageViewer formats. ScreenShot Hack came with a Windows utility to convert the files to Windows-accessible formats.
