What C2 is calling "a new tilemap image" is indeed a tileset.
Here's an example of how you load different tilesets:

Each tileset is a separate image. You can check them in the Files folder in the Project Tree.
Edit: Keep in mind that changing the tile width/height in runtime is impossible, though.
Perfect, then I was wrong, I simply did not know that function and I thought it was just a map load, not a TILESET, I was also confused that the action is called "Load image from URL". I thought it was about uploading a new map from the network by connecting to a web or some server or something.
Thanks !, this eliminates some problems in my game.
On the width and the height, I only need to consult it, I do not need to change it.
Is it possible to consult the values ?.
I do not know how to check the width and height of a tileset.
