passing data from played games to site?

So some things are passed from playeds and displayed on the battles site.
For example awards and winners.
Say if a lua was made that collects some data (eg starting factories, so it is easier to find "that vehicle vs air match"), how would it go onto the site?
Could not figure it out from looking at awards.

Could the same technics be used to pass more data? Is there a size limit?

Also how about svg graphics, they are text. Would this be a way to get some graphics on the battles pages? eg the like the endgame graphs.

There seems to be a size limit. We could pass good economy graphs to the site if not for the size restriction. This data passing is already fully implemented but it would swamp the game over message which made long games (more res data) not appear on the site at all.
