Access forbidden to files linked in description.

Hi,

I'm setting up eDocman on my new site. Everything works fine with documents (pdf) preview and download.
Because some of my PDFs have translations, i use the description field to add links for other languages.

I've noticed that this link can work properly when the target file is anywhere but not in edocman category folders like images/stories.....
When i place my secondary file next to my main file in images/edocman/mycategory/secondlanguage.pdf
i have a "forbidden" access. I have moved my edocman folder in images for managment purposes.
CHMODs seem not involved in this.

Any suggestion?
Thanks
