How big are the files and how quickly can they be seen by an average viewer?
The file sizes are between 50Kb and 300Kb depending on the particular object, number of views and achievable compression. While these file sizes are small and download quickly, it is also important to note that the entire file does not need to load before the object becomes viewable, the first view can be seen in as little as a second and the image becomes interactive immediately as the views download.
