I have made new landscape tiles and i was wondering if there is anything i can do to make dragon place those tiles for me.

Are meaning you've edited the art for certain tiles? If so, then it is a matter of changing the ID values in the maptrans.txt file. Each entry is set for a particular tile ID, so changing those will place the tile ID you want. You have to remember which one you use, or to make it professional, you can change the name on the color table too, just remembering that what ever transitions where on the old tile will be placed with the new tile and may not match. For that, you'll have to edit the transition scripts too.
