I've used your plugin on multiple sites for awhile now and I really like it. However, I've noticed that it doesn't properly resize the window on mobile devices. Well, at least not on iPad or iPhone. This concerns me as my mobile traffic increases.
It's cutting off the top of the photos a bit. Actually, the WP Admin Bar covers this area and the plugin is not adjusting for it. Also, you are unable to see any of the controls under the photos.
