Pentax Optio S5i questions

Hey guys,

I have a couple of questions about the Pentax Optio S5i and I hope that I'll get some response. Thx in advance.

- Is it possible to change the resolution in green mode?
- Is it possible to turn the screen off in green mode?
- Is there a way to set the exif artist/author tag to a value?
- Can the camera detect (exif information) if I take vertical pictures?
- Is it possible to affect picture numbering (e.g. reset to 0)?
