Yes, you're right. The pictures are not saved in the database, only the path/location to the picture itself. So if you remove the picture from your harddrive or move the database to another computer, the paths don't point to the pictures anymore. This is the case for both the pigeon pictures and all files in the media tab. I might have to think this through a bit, maybe find a way to handle this more properly so media files are included.
No problem, just let me know when you have questions and/or problems.
