Little help please

I have just downloaded the tile map maker thing and I looked through the user manual, and it states to use tmw_desert_spacing.png but I can not find it. Did something happen in my download or am I stupid?

Also, does anyone know a good place to get tiles to be used? I am mostly using this for a D&D campaign that I am making.

Probably neither. Not all downloads currently include the examples. Which one did you get?

In any case, the example files can be downloaded directly from the git repository at tiled/examples at master · mapeditor/tiled · GitHub.

Not sure if you’ll find anything suitable, but you could try searching for tilesets on the following sites:
