I use attachement\_fu to store files above the public folder  
so that I can protect them. Only authenticated users are able  
to download the files. Anything works as expected.

But I still have a problem:

If the uploaded file is a image (content\_type = image/jpeg) I want  
to display the thumbnail to the public - the big file is still only  
downloadable to authenticated users.

image\_tag (image.public\_filename) does not work because it looks  
for the filename under /public/…

Any help?
