The application itself offers two buttons, one being "View", which shows thumbnails of the screenshots.
You can view them full-size, but you need to install:
BSD Subsystem
MobileFinder
MobilePreview
You will then be able to use the Finder to navigate into the /tmp folder (which contains the screenshots), and double-tapping one will open it into MobilPreview
(optional but useful installs: MobileText and EditTerm-vt100)
