This is not a new file-format.

JDownloader is already downloading that .zip file containing all of these .jpg files which means if you want to have this as an animated image you will have to use external tools to e.g. create a gif out of all these pictures.

This is not a JDownloader bug or similar - JDownloader is already downloading everything there is from that page
