When creating a new counter you can set the starting value by adding a count parameter to the URL. So if the counter "qwerty" didn't exist, accessing the URL
http://www.klopex.com:80/cgi-bin/counter.cgi?qwerty&COUNT=1234
will create a new counter called "qwerty" with its counter set to 1234.
The counter can only be set when creating a new counter.
Adding the parameter "&show_image=no" will increment the counter but will not return an image.
Adding the parameter "&increment=no" will not increment the counter when returning the image.
