Hi, this is a great plugin.
Unfortunately the PhotoTile layout is not responsive. You can only set a fixed width, so when viewing on mobile phone or tablet it does not do any responsiveness showing.
Can this be fixed?
I'm not a programmer but it should be possible. For joomla there is http://www.svenbluege.de/joomla-event-gallery. This gallery works perfectly with calculating PhotoTile layout on all devices.
