Adding additional image to a product

Please delete

Actually I have a question and I can't edit my original post a 2nd time.

I added an additional picture to a product.
Both images are displayed correctly, however, the larger image on the additional image is not working.
It opens in a small window.
In ImageHandler2, both are defined properly for the default, medium and large images.

Here is the link to the product: http://couchespitchounette.com/catalog/index.php?main_page=product_info&cPath=87_88&products_id=309&language=en

Am I right if I need to use the Large and Medium folders when I use the based zen cart features, but I need to add _LRG and _MED at the end of the filename and keep everything in the base folder when I use ImageHandler2?

Forget my last comment, I have the _LRG version in the right folder, but when I click on the additional image, the larger version does not show the right image
Right image, but wrong size. If I look at the image info, it shows the small image, but when I go to the image handler, the large image is really the large one.
I'm lost, help please
