About GNOME's thumbnails

[Miki <flidon gmail com>]

Hello. I would like to know how to do in GNOME the next Windows XP's action: Windows XP can display the first ones images on a folder's icon, if this folder contains some image.
If this not exist, how can I do it?

Thanks and sorry, I don'y speak English very well (I'm Spanish).
