I see we can add an image on map like this:
import folium
m = folium.Map([37, 0], zoom_start=1, tiles="stamentoner")
folium.raster_layers.ImageOverlay(
image="https://upload.wikimedia.org/wikipedia/commons/f/f4/Mercator_projection_SW.jpg",
name="I am a jpeg",
bounds=[[-82, -180], [82, 180]],
opacity=1,
interactive=False,
cross_origin=False,
zindex=1,
alt="Wikipedia File:Mercator projection SW.jpg",
).add_to(m)
folium.LayerControl().add_to(m)
How to add a control slider to change the opacity of the layer (overlayed image)? I found this leaflet plugin which do the same thing.
