At last, the plugin is working.
It really is a great plugin. Thank you for it.
Still, I think you could make it easier for users to get the plugin working.
You could make a F.A.Q.
Just collect the questions in this forum and write the answer.
Like this in our little chat:
Should thumbnails be created automatically when images is uploaded in media manager?
No, it is not. Thumbnails are created, when the page with images load the first time.
smart_thumbs folder is not created automatically?
/smart_thumbs folder should be created automaticaly. If it is not created, then I think it is not enough permissions to create folder on your server. Set permissions for folders to 755 ( a recommended permission for folders).
I will recommend your plugin everywere I can
