  • Integrates ImageMagick to resize images and create thumbnails.
  • Generates clean, slim, semantically appropriate HTML5 and uses CSS 3 for styling. As a result, the output can easily be themed.
  • Provides HTML access keys for keyboard navigation.



It is recommended to create a virtual environment and run gallerize inside it.

To install ImageMagick and virtualenv on Debian/Ubuntu:

$ aptitude install imagemagick python-virtualenv

This should also give you a copy of pip.

Create a virtual environment called venv in the application path:

$ virtualenv venv

Activate it (note the space after the first dot!):

$ . venv/bin/activate

Install the dependencies of this application:

$ pip install -r requirements.txt


Run with py.test

Install pytest as test runner:

$ pip install pytest

Run tests:

$ py.test

Run with tox

To easily run tests in different Python interpreters, use tox:

$ pip install tox
$ tox

And to test against a single, specific Python interpreter (version 3.4, in this case):

$ tox -e py34


To create a gallery in the directory output from a all images in the directory images:

$ ./ output/ images/*

See the usage help for more information on specifying a gallery title, image captions, and image dimensions:

$ ./ --help
