Question Deleted attached images are still present on disk

(Kunena 1.6.1 on Joomla 1.5.22, all in Russian translation)

In Image Browser I can delete any image which was used as an attachment. It works fine.
But deleted image still exists on disk and physically is not deleted. It will lead to server overfill with images which already do not exist in Image Browser but still exist on server.

All attached images go to /media/kunena/attachments/### folders, where ### is user ID number. So, these folders constantly fill with images although user thinks that these images were deleted, and there is no back-end access to these files anymore.

Is there any way to clean up attached and then deleted images from media folder?

Hello,

Check that the right on image allow the system to delete it (it's need 777 by example)

All images are loaded as Kunena Forum attachments, and are usual jpg photos. These images have no other source.

How this happens:
I just attach a photo as an attachment to Forum post as front-end user, and then I delete this post from Forum. After this I go to back-end Image Management and there I see my photo, and it is said that this image is not used by any post. I press command to delete this image permanently, and it disappears from Image Management as it is removed.
But then I go to the server by FTP to the folder /media/kunena/attachments... and I see that physically image was not deleted and it is still present there. I can easily delete this file by FTP access to website. Annd this happens with all images which were deleted by back-end Image Management section.

I mean check permissions on images to check if it can be deleted

In your kunena.attachments.class.php file you have this:

$this->_db->setQuery ( "SELECT a.* FROM #__kunena_attachments AS a LEFT JOIN #__kunena_attachments AS b ON a.folder=b.folder AND a.filename=b.filename WHERE a.id IN ({$attachids}) AND (a.folder LIKE '%media/kunena/attachments%' OR a.folder LIKE '%images/fbfiles%') AND b.filename IS NULL" );

$fileList = $this->_db->loadObjectlist ();

So it is supposed to get $fileList array with filenames to be deleted. But this array is always 0 in size - it is always empty. After that you delete database reference of this attachment (this works fine), but image file still remains on disk. This is the problem I think - in incorrect database query which always return empty result.

I am not an expert neither in PHP nor in mySQL, so can you please tell me what I have correct in this code above that it work? I really need to clean up my images from forum attachments.
Thanks!

For the moment, i will report this like bug, anyway thanks for report
