Captcha Prompter

• latest version is available here: http://gsbabil.googlecode.com/svn/trunk/prompt_captcha.py

• This tool is written using PyGTK2. It takes an image file name as input, shows the image to the user and asks him to type the text shown in the image. The goal is to use it inside the Unix scripts. For example, one could do 'CAPTCHA_TEXT=$(python prompt_captcha.py captcha.jpg)' in Bash and perform further actions with $CAPTCHA_TEXT. This little tool will accept png, jpg, gif and most other commonimage formats.

• usage: python prompt_captcha.py captcha_image
