Can site users download the map image?

Question

Parsing

There is a gps-tracking service for various competitions (including online broadcasts) o-gps-center.ru/viewer . It is necessary to check whether it is possible to download the map image if the broadcast is not yet available in real time.
This page looks like the screenshot.
Here is an example of a page of an already conducted broadcast viewer.o-gps-center.ru/viewer/event/3734 Map
link /newmaps/map_2831_a1f92674a45478646f264dc166bcf30d.gif
As you can see, maps are stored in the /newmaps directory, the file name is encrypted filename_32-character expression.
And it is precisely important to understand whether it is possible to access the broadcast before it starts and download the map image accordingly.
Ps Perhaps online broadcasts will not always be available.
