Hi

I've seen the screencast Build an Image Streaming App With Node.js. I used this code to generate badges for my local installation of the pub/sub server and the webserver. The code is generating information and they are written to Redis correctly, but no badge is shown, because the path to the image is wrong:
http://192.168.142.158:3000/
img src="ruby-bits-part-2-59098ceb97c12ac640eebadf6a4da58a.png" alt="Code School Badge"

What is the correct path for the image to run all locally? (only point to images on codeschool.com). Or what does I have to change, that my local webserver and pub/hub server is working fine. I would like to have all local.

Thanks for your help.
