WP-Camo

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.

1. Upload the plugin files to the /wp-content/plugins/wp-camo directory, or install the plugin through the WordPress plugins screen directly.
2. Activate the plugin through the ‘Plugins’ screen in WordPress
3. 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.

Images don’t appear

This could be for a few reasons, the most common are:

• WP-Camo could not write to the disk.
• Your web server could not request the image.

1.0.0

• Cache the images on the server instead of fetching them anew each request.
