Hi,
In my opinion, store all of them in a FDB.
1. It will be compact at physical and logical level
2. You will not disturb the OS file list with huge entries.
3. You can decrase application complexity by using only a FDB.
4. You will prevent broken file links
5. There is no storage saving with using external jpg files.
6. It will be more fast.
7. It will be more portable.
8. It will be more backup/replication-friendly.
etc...

Regards.
Ali
