Passes images through the WordPress site to prevent mixed content errors and bypass local filtering.

== Description ==

Supplies filters

Orignal use case was WordPress themes that used images from facebook which in schools was blocked. By _proxying_ the image through wp-camo images from Facebook will now load in school.

== Installation ==

1. Upload the plugin files to the `/wp-content/plugins/wp-camo` directory, or install the plugin through the WordPress plugins screen directly.
1. Activate the plugin through the 'Plugins' screen in WordPress
1. Use the Settings->WP-Camo screen to configure the plugin

There are two settings that can be configured

 * Prevent Mixed Content Errors, which applies a filter to `the_content` which finds all `http://` images and changes them to wp-camo images.
 * Apply WP-Camo to these domains, which will pass images on these domains through wp-camo regardless of if its hosted on https.

In your theme/plugin you can use the filter `wp_camo_hash_url` to get the location of the image through WP-Camo.

`
apply_filters('wp_camo_hash_url', $url);
`

The image's url will be a location in `/wp-content/uploads/wp-camo/`. The image will be downloaded and cached on the server to reduce load.

There are 2 filters for changing the path wp-camo uploads images to.

 - `wp_camo_disk_path` which sets the on disk path of the wp-camo directory.
 - `wp_camo_public_path` which sets the public url of the wp-camo directory.
