I would like to do this exact same thing as well, but I'm using PHPadsnew. I just want to see if I'm understanding the logic in how this solution is being done.
Store the invocation code for displaying the ad in a folder on your site. (In your case the text files are here:
http://www.hotspringshomefront.com/t...s/mwt/banners/)
The smarty code listed in this thread is stored in a php file located in the (68classifieds site/includes/classes/smarty/plugins/"myads.php")
Then you include a call to the smarty function within the layout.tpl.php file where you have designated your ad to be placed.
Is that correct, or am I missing something?
Thanks,
