FREE BANNER ROTATOR <<<<<<<<<<<<<

[|-|erc]

You can charge people to advertise on your site by setting the number of credits which is how many displays
they get.
This is my rotator.txt file, this goes in directory rotator with the banners.

CREDITS BANNER URL
999999995 b1.gif www.milliondollarsurfer.com
999999994 b2.gif www.gamesandstuff.com
994 b3.gif www.belengonzalezauto.com


The php script uses this TABLE data but with a text file instead of setting up mySQL, great for small
tables.

If you try it out let me know how it goes.
