  Step 1

  First I got the RPI set up with the latest and greatest Raspian. Make sure that you up-date up-grade and set the GPIO and Camera in raspi-config. This site has all the information that I started off with even the code I used to get it working at first (camera.py I added stuff to this code to get it to do what I needed it to do I will add this info later.

  Make sure that you get the button working that is important.

  Step 2

  On this next link is where I got the info for sending the photos taken with its own email account .

  http://mitchtech.net/connect-raspberry-pi-to-gmail...

  I tested it by copying the script to send attachments in to the python editor on the rpi by first opening the python editor and then open a new scripting page so you can paste in the whole script at once and run it ( make sure you fill in all the necessary info first or it will not work email address,  where to send it to, etc) I have a dedicated email address for this project you don't have to but it might be best. I will post my script in the next step (3).

  I also started working on the body of my photo booth. I am using a concrete forming tube, blue foam board, and PVC pipe from Lowes for the body. The tube was 4' tall by 12" round. I cut 12" off the 4' tube to give me a head. The photo below shows how I was headed. I used the head as my blue foam templit for cutting.

  You will need at least 4 blue foam board round cut outs. In this photo I noticed that it might be more stable with the head laying side ways and it looks better.... so this is the way it stayed.

  Step 3

  Well in this step I will focus on the code and getting it to work with Facebook and Flickr ....

  ---------------------------------------------------------------------------------------------------------

  It does not look as good on here as it does in IDLE and I dont think you can copy and past it. so I am in the work of getting a place I can post my files for links to them like for here at hack a day.

  I will use it to show where to make changes to make this work. Oh I did not make this script I just copied pices of it to smash it together to make it work for me.   

  # set up the pins

  GPIO.setmode(GPIO.BCM)

  GPIO.setwarnings(False)

  GPIO.setup(24,GPIO.IN)    <- Button input 

  GPIO.setup(23,GPIO.OUT) <- Lite on the button

  GPIO.output(23, True) <- turn lite on 

  # setup variables

  USERNAME = "email@gmail.com" < -you need to put you email you set up                                                                      for this thing here

  PASSWORD = "password" <- password for that email address 

  count = 0 <-starts photo count at 0 

  up = False

  down = False

  command = ""

  filename = ""

  index = 0

  camera_pause = "3000" <- how much time it will preview

  Next 

  command = "sudo raspistill -o " + imageName + " -q 100 -t " + camera_pause <- ok this is the command that is sent to take the photo. (I know now htey have this worked out to do this in python with out using os.system .) you can add options on here from the camera info like polerize of sketch. this is just like typing it in the terminal prompt. 

  Emailing  

  sendMail( ["the emailtheygiveyou@m.facebook.com"], <- they will give you a                                                                                                   email to send to                                                                                                         Flickr does the                                                                                                             same thing

  "test set up for photo booth", <- this can be any thing I see it on facebook as                                                        the photo comments. I have thought to use                                                          "photo-" + timeString + ".jpg" to see what                                                               happens .

  "Test picture attached",  <- so far I have not seen it in any photo so does not                                                 matter what it is.   I think ?

  ["/home/pi/photos/photo-" + timeString + ".jpg"] )   <- this is where the file is                                                                                              to send it

  You can see from the web sites what I copies and what I didn't. With Facebook and Flickr having email uploading makes this work out great....
