Multiple External Images - *New Question*

I know there are several threads about external images already, but I have a new question.

I have been successful at displaying external product images using this method:

http://www.zen-cart.com/wiki/index.php/Contribution:Web_images

My question is how do I now get multiple images to display in the product page? For starters, I have created new database fields called "products_image02", "products_image03" etc. Using EP I have uploaded the URL's of the additional images and I can see them in the database fields. I do not know how to call them from the database to display in product page.

Here is the site: http://www.micmed.com/simpsoncycles/

The main page images are local. The additional images on the product page are in the HTML, but my client does not want to have to do it that way.

To further clarify:

The image names come from another application, so using common basename+ consecutive numbers will not be practical. The images HAVE to served from another location. There are hundreds of items that will be uploaded each week. There are 10 image field URL's that will be uploaded for each item via EP.

Happy Holidays Zenners. Great appreciation to anyone who can take the time to help me with this.
