keeping ads on page??

is there an easy script I can use to keep the ads on the page as i scroll down? demonoid is one of the many sites i've seen that have a script for this.

It's fairly easy if I understand correctly what you're trying to achieve.

check this:
It's done using jquery.

Download the source and modify it to your needs:

Just edit the index.html and put your ads in. But of course you still need to keep the included javascript in place

ooops, i don't know if virustotal is required for html/javascript code, if it is then please someone post it, thanks.
