Hi,
I think, there seems to be a bug concerning the upload of a "feature image" in a multiblog system of Wordpress 3.0:
My bigfeature-blog is a second blog "under" the main blog and its called "atelier" with the blogID "6".
In this "sub-blog" I upload within a new post the feature image like this:

Then opens a window, where I upload the feature image:

Pay attention to the path of the image!
In the frontend of the bigfeature blog there is NO feature image!
When I analyse it with firebug, then the source code of this post is like this:

That means, that in the source code of the post in the browser Firefox, the path of the image is
src="blogs.dir/6/files/2010/03/mikroheader11.jpg" - causing that no image is shown in the frontend
but it should be in the frontend a path like the image of the upload shows:
src="http://birgit-heinz.de/atelier/files/2010/03/mikroheader11.jpg"
Even if I add the complete URL in the BF post settings in a post, it does not show the big feature image of this post.
In this example "6" is the ID of the blog "atelier" when you look at the FTP or when you look in the dashboard of the super admin.
What can I do, so that the path of the uploaded feature image is interpreted right, that means not "blogs.dir/6/files/2010/03/mikroheader11.jpg" but right: "http://birgit-heinz.de/atelier/files/2010/03/mikroheader11.jpg"?
By the way:
I use BFNav 1.0.1 and Big Feature 1.3.5.2
See the problem here:

Above the big heading "MIKRO KUNST" should be over the whole width of the site the big feature image.
Thanks a lot.
