Kittens

A simple django application to show a random image fetched from Flickr resized to a specified size.

/kittens/x/y/js gets javascript to show one of the locally cached images in x pixels witdh and y pixels height. This is the preferred way to show pictures you got from Flickr because it creates a link to the Flickr page of the original image.

/kittens/x/y gets one of the locally cached images in x pixels witdh and y pixels height directly. Flickr author ID and image ID get encoded into the redirected image URL, so this also conforms with Creative Commons license requirement for attribution.

/kittens/fetch fetches a new image from Flickr and stores it in local cache.

You can see live demo at http://theoldreader.com/kittens/

Installation

It's quite easy to launch the app in Debian/Ubuntu environment using gunirorn and nginx:

mkdir -p /var/www/kittens && git clone git@github.com:knyar/kittens.git /var/www/kittens/current
aptitude install -R python-imaging python-virtualenv gunicorn
virtualenv --system-site-packages /var/www/kittens/virtualenv
/var/www/kittens/virtualenv/bin/pip install -r /var/www/kittens/current/dependencies.txt
mkdir -p /var/www/kittens/current/files/images && chown www-data /var/www/kittens/current/files/images
echo "FLICKR_API_KEY = 'xxxxxxxxxxxxxxx'" > /var/www/kittens/current/project/local_settings.py
cp /var/www/kittens/current/project/gunicorn-d.conf /etc/gunicorn.d/kittens
service gunicorn restart

Then add the following to your nginx virtualhost:

location /kittens/ {
  proxy_pass        http://127.0.0.1:8000;
  proxy_redirect     off;
  proxy_set_header   Host             $host;
  proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
  proxy_set_header   X-Forwarded-Proto $scheme;
}
location /kittens/files {
  alias /var/www/kittens/current/files;
  expires epoch;
  add_header Last-Modified "";
}

By default new image is fetched from Flickr when somebody visits the index page. However, you can add curl http://localhost:8000/kittens/fetch > /dev/null to your crontab to add new images regularly.
