Works as described, could be a must-have with gallery support

The plugin does what it say, so 5 stars for full functionality as a minimal viable product and clean implementation (no errors or warnings in debug mode).

However, in order to provide a valid solution for the proposed used case of sharing media across networks, the full media library feature set would need to be supported including gallery creation/modification as well as featured images and media imports through the Media page (without inserting an image into a post).

I’ve heard the API for media in WordPress is still somewhat incomplete as of 4.1, so I understand those ?missing“ features probably are a question of technical factors and of the general development challenges most free plugins have in common.

I’m going to contact the plugin author for a quick discussion of potential collaboration on this otherwise very useful and referable plugin.
