I'm new to Mediatomb having just downloaded it so please bare with me if I'm asking a silly question.

I have setup the autoscan to scan my picture library and for some reason, the last parent folder (last major collection of photos with subfolders) has all the images being served up in thumbnail dimensions to my WDTV Live media player.

Remedies and checks I have done:
- I have deleted the top parent from the databse and had the folder rescanned to no avail.
- I did the above again and restarted mediatomb to no avail
- I deleted everything in the database and rescanned again, and restarted to no avail
Has anyone else encountered the same problem?
Is there a special config I have to do somewhere?
