A short instruction
Works with
Webiopi 0.7.0
RPi Cam Web Interface http://www.raspberrypi.org/forums/viewtopic.php?f=43&t=63276&sid=41a3ead97da35a156cf1fe9f767a8b9a version 14-5-2014

In the Webiopi config file add the location of the html folder and python script folder
sudo nano /etc/webiopi/config
[scripts]
myproject = /home/pi/robot/python/script.py

and in 
[HTTP]
doc-root = /home/pi/robot/html

In my case, I have to flip the camera horizontal and vertical
Change the file

sudo nano /etc/raspimjpeg
-> Find 
hflip false
vflip false

and change to
hflip true
vflip true

I needed to change the preview folder to a subfolder of my html folder
add # in front of 
preview_path /dev/shm/mjpeg/cam.jpg

and at 
preview_path /home/pi/robot/html/stream/cam.jpg

In the index html file add
<div><img id="mjpeg_dest" src="stream/cam.jpg"></div>

and add a custom css file and js file
<script type="text/javascript" src="js/robot.js"></script>
<link rel="stylesheet" type="text/css" href="css/robot.css">

in robot js add 
//Refresh the raspberry pi camera picture every 40ms =25fps
				setInterval(function(){
							$("#mjpeg_dest").attr("src", "stream/cam.jpg?"+new Date().getTime());
							},100);
to reload the picture every 100ms, find the best time to suit your needs

MAybe edit  /usr/share/webiopi/htdocs
webiopi.js to remove google analytics and the webiopi.css

ServoBlaster change the config so only the actual servo ports
