As of this point, I am releasing the List Attachments Shortcode plugin into the WordPress repository. As a result, I’ve included a proper WordPress plugin readme file, as well as the text of the GPLv2 license with the download.
There was only one change to the code between this version and the previous version; but it’s a rather major one. The links generated by the first version of the plugin were empty. This newer version corrects that.
The usage is still the same as the first version.
