New images need to be uploaded to Google Merchant Centre

Ideally, you would have done this previously and understand. The main product images are getting disqualified by Google as they have watermarks. So the manufacturer have a small thumbnail image which apparently can be uploaded to Google in the Merchant Centre feed. So the thumbnail would then appear on Googles search pages, but when customers have clicked through to our site, the original (current) watermarked image is still showing.

Approx 5000 images on the zip file, which should go straight onto the feed.
