pkg-screenshot is a shell script that can display preview screenshots of packages using xdg-open. Screenshots are provided by screenshots.debian.net, so the package must exist in the Debian repositories. Please note that not all packages have screenshots available to preview.
pkg-screenshot requires wget to download screenshots, jq to parse the json provided at https://screenshots.debian.net/json/package/PACKAGENAME and xdg-open to open the image file (saved to the /tmp/ directory)
pkg-screenshot.sh [options] package
-h, --help - Print a help list
--no-download - Open the image URL instead of saving an image file in /tmp/
