It can be used to avoid browsers cache by inserting a random number.
For instance, http://my_url?[random-number]” could generate http://my_url?134548.
[random-number from=”2″ to=”72″ format=”%b”]%d minutes[/random-number]
output: an integer value between 2 & 72 followed by the word ‘minutes’
This plugin is a sample on how to create a plugin which:
* supports internationalization,
* provides an option screen,
* saves some options,
* use images,
* replaces a tag.
By the way, it generates randomized numbers ;o)
