Hello, why do I get this error when I use “add external tileset” ?.

I attach the image that I want to add as tileset.

Hello,  
An external tileset is a file that defines a tileset (attached image(s), width, height, borders and offsets to properly use your image(s)).  
You need to create a tileset using your image first.  
Choose _File -\> New -\> New Tileset…_ to open the New Tileset dialog, and then see the documentation:  
[https://doc.mapeditor.org/en/stable/manual/editing-tilesets/](https://doc.mapeditor.org/en/stable/manual/editing-tilesets/)
