Images can't be seen [Php + data base]

Hello everyone!

I've got a problem with uploading images for my newsletter. I installed fckeditor and everything works.

Let's have a look to my problem : I insert data from my newsletter in a data base, the path for images in config.php is :

// Path to user files relative to the document root.
$Config['UserFilesPath'] = '/userfiles/' ;

The problem is that the code which is saved in the database for the image is "src=/userfiles/images/image_name.jpeg". That's why the image can't be seen, when the newsletter is send. How can I do for the path to be http://www.mydomain.com/userfiles? I doesn't work if i configure $Config['UserFilesPath'] = 'http://www.mydomain.com/userfiles/'

Thanks a lot for your help, please excuse my poor english, I'm french...
