Can I View File Without Signature?

I'v been looking around the website with f12 (developer tool) and found some jpg link.

And the links are consist of key-pair-id, policy and signature.

After little search found that those link element was associated with AWS(Amazon Web Service)

But I get error when I enter the link to view the file

"This XML file does not appear to have any style information associated with it. The document tree is shown below."



MissingSignature

Missing Signature query parameter or cookie value



I think this is because of missingsignature wich file host did not apply signature to link....

Anybody know how to view file without signature?
