A: Hi Mvishal71,
1. The stacking is submitted, waiting for it to be processed :-)
2. Bricks and ZION has not been tested, yet I am confident that it will work, as so far the feedback from the builder crowd has been very positive. On our website there is a free trial for 14 days so you can test it out and let us know your experience without any risks.
3. Only a few images are loaded on page load, the remaining ones are loaded in the background. The order of the images being loaded is using Gauss distribution, so the one likely to be displayed are loader first. But there is a room to improve. We want to add more options for how to load the images ( simple linear, delayed, deferred,waiting on user interaction etc.)
There are also ways how to entertain the user while the animation is loading - like placing it further down the page, or behind a loader.
4. There are a few places to look for if you want to learn how to use the plugin
