Where I can download any maps or mods for WWP? Maps that are drawed professionally, not in MS Paint.

Quite a few of the maps in our cart [second link] are made in Paint, I'd say. Nothing wrong with
Paint if the person using it realises its limitations and knows how to overcome them.

In the end it's a map's playability that matters, not looks. Back when I could still rope, my favourite RR map pack was made in WA's terrain editor.

I wonder what the poor guy had to overcome to make a rr in the terrain editor :P

He was using WA's terrain editor, which is far superior to WWP's.

where do i put the imported maps so i can play them on multiplayer

Which type of file are they (gif, jpeg, bmp, tga, etc.)
