I'm in a similar situation as this user: CDN virtual subdomain causes duplicated content
However, I have yet to create the CDN.
My question has 2 parts:
Part 1: I think I may have found an issue with the accepted answer in the question above regarding duplicate content with images. You see, Google has stated that they don't look at rel=canonical on images.
So my fear here is that I would have duplicate content with all my images, hosted on the CDN. What can be done to avoid this?
Part 2: On an nginx server, how can I make site-wide canonical links?
