Hello there.
I would like to put an ad banner on wpblog1.com and include that on wpblog2.com and wpblog3.com
When it's time to change the ad banner, I'll do that on just wpblog1.com and it shows up on the other blogs too.
How can I include that in a safe way?
http://wpblog1.com/ad01.php
or:
http://wpblog1.com/ad01.html
or:
http://wpblog1.com/ad01.asp
doesn't matter for me, but maybe for the security)
My Wordpress blogs are hosted on Cent OS on Hostgator's Reseller Hosting.
Thanks.
