Comment 1 for bug 918461

There is a work-around for this issue. It surely isn't pretty, but it will allow you to keep SEO activated:

Open your FTP client.
Go to the location where the file is stored. (i.e. 1.news.php)
Download this file.
Open it locally. Seek the link location and change "images/news.jpg to "http://www.domainname/pluck/images/news.jpg".
Do so for each image.
Save the file, upload and overwrite the original file on the server.

Not a pretty solution, but so far the only thing that worked for me without messing about PHP code.
