This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

WP Read-Only


This plugin was made with cluster/load balancing server setups in
mind – where you do not want your WordPress to write anything to
the local web directory.

WPRO will put your media uploads on Amazon S3. Unlike other
S3 plugins, this plugin does not require your uploads to first be
stored in your server’s upload directory, so this plugin will work
fine on WordPress sites where the web server have read-only access
to the web directory.

  • WordPress image editing will still work fine (just somewhat slower).
  • Full support for XMLRPC uploads.

This plugin was made for WordPress sites deployed in a (load balancing)
cluster across multiple webservers, where you do not want your WordPress
to write anything to the local web directory.

Note: You still need write access to the system /tmp directory for
this plugin to work. It will use the system /tmp directory for
temporary storage during uploads, image editing/scaling, etc.

WordPress MU

We did not test this plugin in a WordPress MU environment.
It will probably not work out-of-the-box for WordPress MU.


  1. Put the plugin in the WordPress /wp-content/plugins/ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Enter your Amazon S3 settings in Settings > WPRO Settings.


Will this plugin work in WordPress MU environments?

Probably not, but I am not sure. Input and/or code is very welcome!

What should I think of when digging the code?

If you define the constant WPRO_DEBUG in your wp-config.php, then
some debug data will be written to /tmp/wpro-debug

What about the license?

Do you like beer?

If we meet some day, and you think this stuff is worth it, you may buy
me a beer in return. (GPLv2 still applies.)
