Create map isometric 2D help

Hi Guys!

I want to create 2D map with Isometric Images and later put 2D isometric characters on map and move them on the map.

I know how to create map with grid and tiles for 2D game, but im stuck for isometric.
My grid is on 2D axis but images are on isometric 2D.

What is the good way to do this?

TY
