So, the new version is out. You maybe noticed that the flash slideshow is no more working. In this case please check the path of the imagerotator.swf in the gallery options -> slideshow.
If it’s empty or point to the plugin folder, you should upload it again to your upload directory. You can use the WordPress Media uploader or you upload it via FTP. Then press in the gallery options the button “search now”, the correct URL should be entered automatic, otherwise add it manually.
Why do I removed the slideshow from the plugin package ?
Now, the basic issue is based on the fact that my plugin is released under a GPL license, but the great Imagerotator is published under a CC license. To respect both license, i decided to remove the flash file from the package. It doesn’t mean that I didn’t support it, the slideshow is still a core feature.
As always : Please report further problems at the wp.org forums.
