Thank you for your post.
You see, image upload is a time consuming process. However in most cases, it is a single time process.
You should try to restart the image upload in the Store Manager, or proceed with the reimport.
In your case, image upload may take up to 48 hours and that is normal considering the amount of imported products and their images.
