I need to create a folder that will contain pictures for a game application.
There can be up to 50MB of pictures.

The problem is I don't want to see these pictures when using the Gallery application but at the moment all these pictures are visible there (making it difficult to browse "real pictures").

I cannot put these pictures to the private folder of the application because the user should be able to add pictures (dynamic download of new game levels).

1. How can I have that kind of folder with pictures that won't show in the Gallery application?

2. Is it possible to hide a directory?

3. Is there any other locations for the folder else that the application private folder and the Data folder?

Thanks in advance.
