     The *Tile* and the *Information sheet* configured through this option will be automatically used for all layers loaded from the involved catalog source (if not configured the default *Tile* used is `image/png` and the default *Information sheet* used is`text/plain`). For layers already loaded on the map, it is possible to change the format through the [Layer Settings](https://mapstore.readthedocs.io/en/latest/user-guide/layer-settings) tool as usual.
