I have had an issue for some time now with picture thumbnails not working when viewing Amazon on Safari. If I copy the web address and use another browser the thumbnails open just fine. Any ideas why this is happening?
Do you mean the thumbnails don't respond when tapping, or that they don't appear? Just curious. I only have one suggestion either way.
You can try going to Settings > Apps > Safari > Advanced > Website Data. Search for and delete anything Amazon. You'll probably lose your saved longin info, so make sure you have your password ready.
This will help if you have any old stored data that is interfering with the site loading properly. It's rare, but it does happen.
