Large image not working on new products.

I loaded some new products and images on Zen Cart. When I go to view my new product online it is shown ok but when I click on "Larger image", to see if it works only a smaller image shows. If I go and check on older products I had entered the Larger image is working fine.

I have checked on my hosts system and the larger image in sitting in correct place in Large Images folder.

This problem only occurred in the last batch of products and images I loaded onto Zen Cart.

Does anyone know the solution to this problem?

Based on the description of actions taken and existing condition, it sounds like the image being chosen by ZC as the lrge imge does not hve a dimension as large as your other large imaages. If your large image is loaded separate from your other sized images either is not named and stored to be loaded as the large image or the large image file is not stored at the size desired to be presented as the lage size...

This is based on the fact that other large images are loading correctly. The other remote possibility is that this product is aa different product type than those that work poperly and that product type handles images differently. Remote because that would be a rare likelihood and abnormal.

Another test would be to briefly change to the default template and see if the result change. If not then still points to the stronge likelihood tht the saved image is in some way wrong.
