1. About Lazy Load, we are planning to add it in one of the next versions of the plugin for you. I will inform you about the update.
Also you can read more about Load More button inside our Gallery, perhaps it will suit your needs till that time.

Yes. I think you should implement Lazy Load because its very important for your plugin to have it. With Lazy Load, automatically will load the images when srolling down, and that will make the page faster. Personally I am not a big fan of the “Load More” button to be honest… I like Lazy Load much more. So I really hope you will include Lazy Load soon: )
We have already released the Lazy Load feature for you in the new version of the plugin. Please update the free version, clean cache and cookies. Now you can find Lazy Load on the Main Settings Tab – http://prntscr.com/hv3krc
