Hey Art, I do have it set up like that. There is a script to buy, install it... but you will have to edit it based on your dolphin site...size of the banner, type and so...
You can install it in a separate domain or folder where your dolphin sits....
For you and others interested.....
Live demo ( please do not sign up just to see) If you want to get in, use name testera ; pass testera
domain; cmok cafe dot com ( or yuropean dot dom - waiting for dolph7 to finally change the name and I dont want google to search for my site here so I type it like this) and hit marketing link in upper right corner.
The site name I use the advertising script is adsvibe dot com. Most of it is in my language now so you might not understand it but you will get the picture.
http://phpwebscripts.com/admanagerpro/index.html is the site I got it from.
You can edit it any way you want, any type of banner, and their support is more than great. I got familiar with it so if you need help, let me know.
I personally hate Google and Adsense, I dont see how 50000 impresions and 150 clicks make $1.50???
Let me know if you have any more questions...
