All you have to do is to select the directory where you stored your images, the module does the rest of the work, like dynamically creating thumbnails.
Since the output is completely responsive, you'll always get a optimal display on every output device, provided your template is also responsive. In the backend, you can control how the gallery should look in the frontend, for this, there are many self explanatory settings, from defining width and height of the thumbnail to duration of the fade effect.
The module is completely styleable by CSS, the output has been separated from design. This allows even better adjustment possibilities to your template, if you want to adapt the modules theme to the template.
