I'm using the Azure Maps web API to show some images on top of a map. I plan to use the image layer function to do it, but I do not want my images to go to Microsoft servers. If I use the image overlay, does it process the images locally on the user's computer or on Microsoft servers?
The Azure Maps web API (as well as the mobile SDKs) don't send any data you overlay on the map to the cloud (tiles, images, points/lines/polygons...). All rendering is done locally within the client session.
