It seems normal to me that any slideshow support Lazy Loading of images in the gallery. However, in your FAQ you suggest that it does not. Once the page has loaded the user should be able to start interacting with the slideshow (via the entire thumbnail carousel) while the fullsize images continue to be "buffered" in the background.
You don't need to download ALL images, just the next few. After all I may have 100s of images in 1 single post (we're not even talking 10 posts on a page here) in my gallery in a slideshow (thats what photographers like me do).
The user should also be able to navigate to any image (even if not buffered) and the slideshow should retrieve that one on-demand if so required & buffer the next few right after.
How long before you can make these changes?
Thanks for the beautiful plugin.
