In the game list, maps made by blizzard (i guess) show a little blizzard logo with a check mark on it. Is this part of battle.net or part of the map? And is there any way to make that image, or another image, show up on one of your maps before the name?
I don't think you can make images like that.
A long time ago people used to change the logo. Most times it would make the map corrupted thus unplayable.
All of blizzards map melee and UMS maps had the blue blizzard thingy with the check mark. I dont think we can cahnge the logo.
Let me be a bit more clearer on this.
There used to be a hack the let you change the logo but most of the time it corrupted the map.
It has to do with the actual battle.net client, so no it cannot be changed.
Not like it would change alot anyway to have Blizz next to your maps -.-
like BeerKeg[em] said there used to be a hack that would let you put or change an icon there, but thus putting it there would curope the game and make it unplayable so no one uses the hack now...

Great, starting to repeat already...
