How not to repeat the same attributes in each fotorama gallery.
Create file fotoramaDefaults.js
in the /wp-content/plugins/
directory and list your options like so:
fotoramaDefaults = {
nav: 'thumbs',
allowfullscreen: 'native',
transition: 'crossfade',
loop: true,
keyboard: true
}
Fotorama will try to fetch the options from the /wp-content/plugins/fotoramaDefaults.js
.
