# Simple script to snap photo with digital camera and post result.
# photoAutoBlog.sh uses gphoto2 to control a digital camera installed
#   with power in a preset location.  The script prompts the user for
#   information to be posted alongside the photo (questions about food
#   in this version of the script) and gives the user a preview of the
#   shot.  The script then saves the photo in its original format in
#   myOrigPhotosLoc, scales the photo down for two different web sizes 
#   with the "convert" command, and uploads all the images and text
#   description to the blog site.
#
# Run from the command line, the script first asks if the meal was
#   eaten out.  
#   Meal eaten out? <y/N> 
#   If you answer "y" or "Y", the script then asks for a restaurant 
#   name and generates a place holder image for the blog.  
#   If you answer "n" or "N" or hit enter, the script generates a 
#   pop-up asking for a short description of the food.  This is saved
#   in a simple text file.  The photo is then taken with the zoom
#   and flash settings specified in the "gphoto2" line below.
#   Lastly, the script uploads the photos to a directory created for
#   that purpose on the wordpress site using rsync.  The remote 
#   directory contains four files for each run of the script, for
#   example:
#   -rw-r--r-- 1 xuxa xuxa      53 2010-10-04 17:48 101004_174736.dat
#   -rw-r--r-- 1 xuxa xuxa 1066874 2010-10-04 17:48 101004_174736.jpg
#   -rw-r--r-- 1 xuxa xuxa  318464 2010-10-04 17:48 101004_174736_m.jpg
#   -rw-r--r-- 1 xuxa xuxa   13307 2010-10-04 17:48 101004_174736_s.jpg
#   The first set of six letters represents the date in yymmdd format
#   and the second set of six is the time the photo was acquired 
#   hhmmss.
