AWS: "ERROR: The request could not be satisfied."

I am trying to use curl to push my images of my Rails project to my AWS CloudFront distribution with a POST request. However I get the following error:

Here is how I made the request:

curl --data @general.png http://ift.tt/1ttIYw1

And this is the error i get:

ERROR: The request could not be satisfied
This distribution is not configured to allow the HTTP request method that was used for this request. The distribution supports only cachable requests.

I don't know if I need to create a 'Bucket' for my distribution. I also don't know where/if I can set up my distribution to allow this kind of approach to uploading Objects to my distribution.
