Is it possible to use an url instead of just typing "osm"?
My guess is, that you can get an API-key for OSM on their website.
If you have this key, then, if it is posibble in XnView, and paste that url, you should see the map without the watermark Api Key Required.
I have an API-key for OpenCycleMap. I've pasted it instead of "osm" but it reverts back to Google.
Is it possible, that I can use an url instead?
Here is an example how it looks:
https:// tile.thunderforest.com/cycle/{z}/{x}/{y}@2x.png?apikey=xxxxxxx
You would make me, and I guess some other users, very happy.
Edit:
I just took a look on the website of Thunderforest.
You can get your own API-key there if you want, and if you choose "Atlas" as view, you get the same result as in XnView.
Here is the an example:
https://www.thunderforest.com/maps/atlas/preview/
So, In XnView the url should look like this: https:// tile.thunderforest.com/atlas/{z}/{x}/{y}@2x.png?apikey=xxxxxxx
Now it just depends on the developer to implement the use of an url, and you're good to go
