Regarding the avatars, it's simple – they are linked to, and stored separately in a folder. You will need three avatars: (Left/Right/41x41 pixels for trio duels in the hero selection menu).
Do I need to create them from scratch and change them constantly, or are there ready-made ones for all heroes?
My point is that, at least as far as I can tell, there are a total of 104 heroes in the game. I have no idea which 24 (3 * 8 races) of them will appear and in what order if they are generated automatically. Does this mean I need 104 (or 104*3) images? And will they cover both cases shown in the second screenshot?
And regarding the first question, how do I make it so that not 3 heroes are used, but, say, 4 – is there anything I can do about that?

Here /topic/15111/ is a screenshot showing the problem; I've also duplicated it here separately. If there aren't any ready-made images, that's a problem – I definitely won't be drawing them myself
