Product Info Page Additional Images Not Displaying After Upgrade

Just upgraded from Zen 1.3.7 to 1.3.8a. I am using the "gloss blue" template. I have additional images that used to display in 1.3.7 on product info page for each item. After upgrading those additional images no longer appear. The images are in the correct folder and named correctly as none of this has changed. Any help greatly appreciated.

Thanks

give us an example of the names you've used for:

1. a product's MAIN IMAGE
2. the product's ADDITIONAL IMAGES

I was able to correc the problem iwth additional images not showing. My original images were labeledl

Example:

In \Images
LS-golfer1.jpg
LS-golfer2.jpg
LS-golfer3.jpg

In \Images\Large
LS-golfer1_LRG.jpg

The fix was to rename/upload as follows:

In \Images
LS-golfer.jpg
LS-golfer1.jpg
LS-golfer2.jpg
LS-golfer3.jpg

In \Images\Large
LS-golfer_LRG.jpg

I have text though under each additional image that says "large image". Is there a way to remove that from under only the additional images?

Also How can you change the wording above each additonal image?

Thanks so much
