How to upload files straight to S3 without using local storage? [closed]

I’m looking for a WordPress plugin that would allow me to upload files straight to

We are a development shop that actively co-creates CMS websites with clients. This means that we are often iterating sites that clients are using and uploading files to. In our projects, we store the database and code in a git repository which makes it easy to move code from production to local development.

The problem with this process is that some of the files that clients upload are very large and we do not want to upload them to the repository, but we would still like to be able to access them as if we have them.

So, I thought, instead of moving the files around we could just use a 3rd party that would host the files and we would just access them. I could use Amazon S3 with a backup plugin, but I would prefer to just upload to S3 through the admin interface.

The second reason for wanting this plugin is that we hosts blogs that have 20-30GB of high resolution images. I would prefer to not keep these files on our server because server space is expensive. Its less expensive to use Amazon S3 to host the files.

In conclusion, is there a plugin that allows to use the WordPress Media upload, but it will actually bypass the local storage and upload files straight to the server?

Thank you in advance for your answers!

I had this same requirement: my VPS lacked disk space, but I still wanted to manage photos with WordPress. tantan-s3 did not suffice, since a copy of every photo is stored locally.

It’s possible to abstract file storage using PHP stream wrappers, but a couple pieces of core WordPress are incompatible. So that’s the short answer: WordPress natively doesn’t support enough functionality to make this possible.

Moving on: WordPress ticket #18543 concerns itself with patching core to support stream wrappers in imagejpeg() (and other GD functions) and wp_mkdir_p().

Zend_Service_Amazon_S3_Stream provides an S3 stream wrapper, but it tends to be inefficient, requesting the default 8192 bytes at a time rather than buffering more, generating a huge number of requests in the process. I’ve been sitting on this for months, so I might as well release the mods into the wild. This patch works against Zend Framework 1.11.10.

Completing the circle is a plugin to translate the upload path to S3.

I would love to see someone take this further than I have, but it won’t get far until core WordPress improves stream support.
