Popups and popunders?

[jdavidw13]

When you want to advertise on a site using popups and popunders, do you normally have to write the popup script yourself, or does the site do that and you just supply an image or whatever?

usually they suplly with a script like this
<script src="theirs.js"></script>
//html code
they tell you to put it on your site somewhere.
