Poster Screen Lazy Loading

Hi,

I am wondering if Roku's poster screen lazy loads the images, suppose I provide a URL for the sd and hd poster, as the user scrolls the hidden posters into the view. Or, on the other hand, it tries to fetch all the images at once when I populate the list of posters at the first place. If this is the case, would the performance of the box slow down significantly or be out of memory when I have 500 image posters to download.

Thanks for your feedback.
