Random File Picker

The script simply takes the name of a directory and returns a random file from within that directory. An example of its use is provided by means of script to play the game Scissors/Paper/Stone. For a live use of this application, the author uses it to simply manage links from his site, it's quick and easy to add, amend and delete the html link code into files in several directories, and keep thus the links separate from the html formatting of the page. Once a random filename has been selected, the uses of it are vast, as in the example the contents of the file can be displayed or parsed, or for an image file the contents could be displayed via an IMG tag.
