Forms a collage of pictures vk.com when fasting?

Good time of day. That was interesting - if you post ( upload ) some pictures in the VC, pictures are going to collage and so successfully...
maybe someone knows how and what is this?

Solution
first, when you download it creates a lot of thumbnails in different formats
second, the script selected combinations of these thumbnails
You met examples of work, except for the VC or MB seen just an example..? - tre.Cormier25 commented on July 8th 19 at 15:38
I think that it is still individual development of the VC and clearly the development team.
so an example of where to see - hardly - Durward_Osinski commented on July 8th 19 at 15:41
