Broken in what way? …
But regenerating the thumbnails simply outputs “undefined” for all images, destroying all “thumbnail meta” stored in the database.
In answer to these: plugin v2.1.3 does not handle an error contained in the AJAX response, replacing it with “Undefined”. Specifically, the plugin does not display an error shown in the AJAX response (shown in Firefox w/ Firebug) which is thrown by the imagejpeg function in wp-includes/media.php:
<b>Warning</b>: imagejpeg() [function.imagejpeg]: Unable to open ‘/path_truncated/wp-content/uploads/2010/11/filename.jpg’ for writing in <b>/path_truncated/wp-includes/media.php</b> on line <b>453</b>
In this case, the status msg “Undefined” was caused by an error in the WP imagejpeg function, due to 755 permissions on the directory “../uploads/2010/11”. The directory 2010 and subdir 11 were both created manually, after manual (re)installation of wordpress and manual (re)creation of the uploads folder, and manual (re)FTP of all attachment image files.
To summarise, seems like a fix is needed in the plugins parsing of the AJAX response.
