Pictures showing up where they shouldn't

Hi,
I've had some items in a store for a while and have finally got around to adding images to them. These newly added images are now showing up below another list of items and I can't figure out why.
The site is https://www.fineline.uk.com/zenshop
To view the error, go to Studlite => Studs and click on any of these items. You will notice the images for the Terminator item and Extension item showing below the stud picture.
Please help. I don't know why it's doing this!
Thanks in advance,
Glenn

I've figured this out now. I presume it's due to the multiple images thing built in to Zen Cart.
The image name for the main item was stud.jpg and the image names for the other items were in the format stud_item.jpg. I presume that Zen Cart loads in all images that share the same name as the item as well as all images in the format itemname_anything.jpg.
I'd love to know if it's possible to turn this off.
Cheers

If you do not want to use any additional images there is a switch to turn them off in the Catalog ... Product Type ...

Click on the Product Type and hit Edit Layout button:

Show Product Additional Images
Display Additional Images on Product Info 0= off 1= on

Awesome, thanks.
