Why are there no more images revealed by New Horizon? Since a few days after the flyby there are no more images published on the NASA page.

Why is NASA waiting to publish any more images for some reason?

Or is there something happened to New Horizon?

  The transmission of the High Priority data set will be complete on July 20, and then image transmission will pause. For nearly two months, until September 14, New Horizons will switch to near-real-time downlinking of data from other, so-called "low-speed" instruments while it transmits just housekeeping information for all of the rest of the data. No new images will arrive on the ground during this time
