Nautilus Preview

[Paul Wellner Bou <paul purecodes org>]

Hello,

I am using Gnome and Nautilus as file manager and I wonder if there is a 
way to customize the preview feature a little bit more.

I would like to preview images, but only images. No videos, PDFs or 
anything else. I did not find anything regarding this in the preferences 
nor in the gconf settings. Is this possible?

Then I noticed that nautilus is not displaying right the "index.theme" 
files in the theme directories of in ~/.theme. Nautilus displays the the 
name of the theme instead of the file name. Well, this wouldn't be so 
bad, but this way I am not able to open the file 'normally' with a text 
editor. What is nautilus doing there? Is there a way to change this 
behaviour?

Thank you very much.
Regards
Paul.
