After well over a year, I have finally released Open Picture Window v1.3.
It’s been tested and works perfectly on WordPress 2.6 and above. It should also be compatible with versions prior to v2.6.
I’ve added the plugin to WordPress Extend, so you can find the latest version of the plugin available for download from there itself.
The folder name has been changed to
ald-openimagewindow, so in case you are upgrading you will need to delete the
ald-openpicturewindow folder from
/wp-content/plugins or WordPress will throw up activation errors.
