HPR4184: Use GKRellM, wget and ImageMagick for a live slideshow

This segment is about image magic and the GK Relim system monitor and highway web cameras. The British Columbia HighwayCams website allows you to view highway conditions, traffic, and weather information at a glance. GNU Wget is a free software package for retrieving files using HTTP, HTTPS, FTP and FTPS, the most widely used Internet protocols. It is a non-interactive commandline tool, so it may easily be called from scripts, cron jobs, terminals without X-Windows support, etc. ImageMagick is a free, open-source software suite, used for editing and manipulating digital images. It can be used to create, edit, compose, or convert bitmap images, and supports a wide range of file formats, including JPEG, PNG, GIF, TIFF, and Ultra HDR. GKrellM is a single process stack of system monitors which supports applying themes to match its appearance to your window manager, Gtk, or any other theme. Here is how the thumbnails and my own GKrellM monitor look: The bash script can be found here.
