How to add multiple images to product?

I don't get why there isnt an easy way to do this. The only way I found so far was doing this:

https://www.zen-cart.com/tutorials/index.php?article=58

Which seems really complicated. Is there any plugin that I could use to add multiple images to a product?

No, there isn't an add-on. That is the easy way to do it. All you have to do is follow the naming convention. Zen Cart will do the rest.

I did everything the tutorial said to do but still it's not working for me:

http://www.postapocalypticgear.org/store/index.php?main_page=product_info&cPath=2&products_id=2

The site looks good. Unfortunately, it's not possible to tell what the issue is.

The image being displayed is images/fox_claws_earrings/fox_claws_earrings_01.JPG. What are the other images called and where are they stored?

The other images are:

images/large/fox_claws_earrings/fox_claws_earrings_01_LRG.JPG
images/large/fox_claws_earrings/fox_claws_earrings_02_LRG.JPG
images/large/fox_claws_earrings/fox_claws_earrings_03_LRG.JPG

images/medium/fox_claws_earrings/fox_claws_earrings_MED.JPG

I also tried using this add on:

http://www.zen-cart.com/index.php?main_page=product_contrib_info&products_id=1554

and it lets me upload the images but it doesnt show it on the product page!

Does anybody hve a working example of a page with multiple images on a product? I want to know how it looks so I can try to figure out if I'm doing something wrong.

I figured out that my problem was that my file rames were too long, I made them shorter and now its working fine. Thanks for your help AFO!
