I release a new version of my thumbnail management system, post-thumb revisited. New functionnalities:
- add cURL support for remote images
- add rounded corners. Thumbnails can be saved with rounded corners.
I've also added some more informations in the admin panel to ease the installation/configuration.

The plugin is also available on the plugin repository of wordpress.org.
