Hello and thank you for your time and excellent work. :)
Still, we try your plugin and found couple of "weird" behaviors.
(here are our settings: pic01, pic02)
1. When we click on the image we get an altered url like: http://mysite.com/2013/08/03/who-we-are/#lightboxgallery-I8xm/0/
2. When NOT having a responsive theme, the overlay does NOT extend all the way to the end of the page (on a mac and the Chrome browser).
3. We also have a similar issue as http://wordpress.org/support/topic/help-image-very-small-in-prettyphoto .Only in our site although the proportions are constrained, the images themselves (on a small screen) are very small. Much smaller than what they "should be". And as you notice we do have the "right" settings for video. I guess it has to do with the padding. If so, shouldn't/could the padding change proportionally for smaller screens?
Can you please see to them?
