This simple screenshot script utilises both a development addition to PITC and the PHP GD Image Extension.

Install the PHP GD Image Extension known as "php5-gd" then load this script.

Both /ss and /screenshot will output a screenshot of the current window into a directory named "screenshots".

You must have PITC v1.1 from the GIT in order to use this, v1.0 lacks a few tweaks in the Core Code that enable this script to work.

I hope to follow up with a screenshot uploader extension script to enable you to upload the image and obtain its url.

Hope you enjoy.
Thanks!

Edit: Output is now larger as it were originally hard to see.
