Hack 15 Photo Blog Automatically with the Nokia 3650

Instantly publish your photos from the road,
without even logging in.

To me,
digital
photography is something of a mixed blessing. The instant
gratification of being able to view your photos immediately is many
times offset by two small details: you need to have your camera with
you and it has to be charged. My camera is much too large and fragile
to carry with me all of the time, and I'd hate to
have yet another device to keep track of and plug in at night. This
means that I end up with lots of
"event-style" photos, but
relatively few impromptu snapshots of daily life. All too often, by
the time I run to grab the camera, the moment has passed, and the
perfect photo is gone forever.

A number of manufacturers have realized that there is a device that
people habitually carry with them and nearly always keep well
charged: their cell phones. Nokia has managed to merge a whole slew
of nifty technologies into their 3650 phone, including Bluetooth,
GPRS, GSM, and of course, a digital camera. This leads to all sorts
of fascinating possibilities. Not only is it simple to upload photos
to a laptop using Bluetooth, but the interface for sending photos via
email is also dead simple. As if IM spam weren't bad
enough, mankind is now developing the ability to spam each other with
video.

Rather than
throw photo bits at your friends and relatives, it is much more
efficient to publish your photo album to a web page, and IM your
friends and family the link to it. With a little bit of scripting fu,
it is straightforward to have a script that will accept an email and
publish it to a web page.

The Code

First, you need to have your script accept email. This is easily done
with a procmail recipe. Add this to your
.procmailrc on your mail server:

:0 
* ^TO yoursecretaddress@yourdomain.com
| /home/username/bin/phonecam.sh

Of course, change
yoursecretaddress@yourdomain.com to the email address that your photo server will use, and
fix the path to the following script to point to a real directory.
Keep this address private, because any images sent to it will
automatically be published! If you're not running
procmail on your mail server, consult your friendly neighborhood
sysadmin for assistance.

Next, save the following code to a file called phonecam.sh
in the directory you specified in
your .procmailrc. You can download the original
from http://freenetworks.org/~mattw/badsoftware/phonecam/
(this copy has been edited slightly for size). Edit the variables at
the top to suit your system.

#!/bin/sh
#phonecam.sh
filepath="/home/username/public_html/phonecam"
imgdir="img"
html="html"
time=`date +%s`
baseref="http://yoursite.com/~username/phonecam"
title="Phonecam v.3"
arcdate=`date +%D |sed '''s/1//./g'''`
perpage="16"
umask 062
if [ ! -f $filepath/count ]; then
echo "0" > $filepath/count
fi
if [ ! -f $filepath/arc.txt ]; then 
touch $filepath/arc.txt
fi
if [ ! -d $filepath/archive ]; then 
mkdir $filepath/archive
fi
if [ ! -d $filepath/$html ]; then 
mkdir $filepath/$html
fi
if [ ! -d $filepath/$imgdir ]; then 
mkdir $filepath/$imgdir
fi
count=`head -1 $filepath/count`
mkdir ~/.$$
cd ~/.$$
munpack
for i in *.jpg; do
a=`basename $i .jpg`
mv $i $filepath/$imgdir/$time.jpg
convert -resize 320x240 1
$filepath/$imgdir/$time.jpg $filepath/$imgdir/$time.thumb.jpg
convert -resize 150x90 $filepath/$imgdir/$time.jpg $filepath/latest.jpg
# make the new page 
cat $filepath/new.txt > $filepath/new.tmp
echo "<a href=1"$baseref/$html/$timel1"> 
<img src=1"$baseref/$imgdir/$time.thumb.jpg1"
width=1"3201" height=1"2401" border=0></a>" 
> $filepath/new.txt
cat $filepath/new.tmp >> $filepath/new.txt
rm $filepath/new.tmp
# make the individual photo page 
echo "<html>
<head><title>$title</title></head><body bgcolor=000000>
<center><img src=1"$baseref/$imgdir/$time.jpg1" border=1></center><p>" 
> $filepath/$html/$timel
cat $a.desc >> $filepath/$html/$timel
echo "</body></html>" >> $filepath/$html/$timel
count=`expr $count + 1`
done
echo $count > $filepath/count
if [ $count = 1 ]; then 
echo "There is 1 image in the queue" > $filepath/notify
else
echo "There are $count images in the queue" > $filepath/notify
fi
if [ $count = $perpage ]; then 
echo "<html><head><title>$title</title></head><body bgcolor=000000><center>" 
> $filepath/archive/$timel
cat $filepath/index.txt >> $filepath/archive/$timel
cp $filepath/new.txt $filepath/index.txt
rm $filepath/count
rm $filepath/new.txt
cat $filepath/arc.txt > $filepath/arc.tmp
echo "<li><a href=1"$baseref/archive/$timel1">$arcdate</a></li>" 
>> $filepath/arcn.txt
cat $filepath/arc.tmp >> $filepath/arcn.txt
rm $filepath/arc.tmp
mv $filepath/arcn.txt $filepath/arc.txt
echo "There are no new images in the queue" > $filepath/notify
fi
rm -rf ~/.$$

In addition to this script, you need a copy of
munpack
(to decode mime attachments) and
convert (part of the Image Magick suite).
These tools are available in all standard Linux distributions.

Finally, create an index.shtml
file in your web
server's document root that contains a line like
this:

<!--#include virtual="index.txt"-->

For a more advanced example of what you can do with the
index.shtml file, take a look at the example
available at http://freenetworks.org/~mattw/badsoftware/phonecam/index.shtml.txt.

Running the Hack

With all of the above in place, simply send a photo via email to your
secret photo email address. The script automatically decodes the
email, creates a thumbnail, and puts the photo into a queue. When the
queue accumulates perpage photos, it rotates in
the page full of photos, and moves the old page into an archive. You
can always access the latest photo at
http://server/~yourname/phonecam/latest.jpg, and see the
entire pending queue at http://server/~yourname/phonecam/new.txt.
The script manages the queue and archives without any
intervention, and will even post an optional description of your
photos. Just add a text body to the email and it will be inserted as
the photo's description.

This script could probably be simplified and improved, but this
simple shell script should run on just about any server. It creates a
simple but powerful archiving web interface that is easily integrated
into a weblog or other existing web page. And it pushes the instant
gratification of digital photos even further, into the realm of
instant publication.
