went to few sites, found some linux screen shots, included from DirectFB, gentoo linux...etc

dunno how they do it, but basically you can see your wallpaper from whatever program you are running. lets say you open a shell/ konsole, then all you see are the command lines, the background is your wallpaper (that is the section which is being covered).



like this for example:

they are so cool, if u know how to do this, would u please teach me?

thank you

A lot of konsole terminals have transperency option (if that's what you mean). Try Eterm or aterm.
The window manager seems to be GNOME, so you can use it to 'make' 'better' screenshots, if that is the style you like
About making Xchat transparent.. I'm not sure, haven't use 2.02 version. Maybe it's some kind of option from the menus. I prefer BitchX. You can run it in aterm and have transperency, too.
Tha last shot's wm seems to be fluxbox, nice for taking shots, too The konsole terminal is Eterm with some sort of applied color theme.
I prefer aterm, though.
Here's something that I like more than these shots:

Best wishes.

what's diff between eterm, aterm and xterm? somehow they all look alike to me :P

they have different options to choose from, for example aterm and eterm have transparency but xterm doesn't have.
