How do I use FineUploader with Wasabi?

NOTE: Currently FineUploader does not work with Wasabi and throws the following error while uploading a file - Invalid according to Policy: Policy Condition failed: [“eq”, “$Content-Type”, “image\/png”]

This is because currently Wasabi does not handle CORS exactly as Amazon does. It is a future enhancement under consideration.
