Of course there’s browsercam.com (pay) and iCapture (free but groaning under the load!) … but I want a bit more control and a bit more speed. The latest effort appears to be http://browsershots.org (which is in Beta) which will be a distributed screen-cap program, as far as I can see. Looks great! Oh and there’s lixlpixel too … http://fundisom.com/g5/ (which only has a few browsers).

Then there are various kde based options:

* ksnapshot
* gimp

Then command line options:

* import (part of ImageMagick)- “import -window root screenshot.png”
* xv -grabdelay 2 myimage.jpg
* fbgrab filename.png
* scrot
* xwd (X Window Dump) and xwud or gimp to convert the resulting file to a readable format!

Using imagemagick […] import -window root screenshot.png

gimp

Framebuffer Console

fbgrab filename.png

kde

ksnapshot lets you with ease grab a screenshot of your desktop or a single window.

scrot

scrot is a small (66 kB) screen shot grabber

xwd

xwd can dump screenshots to .xwd files the only programs I found capable of opening it were Gimp and xwud
