This article will go over the Image View mode within the iTwin Viewer feature.
Image View is mainly useful for showing photos of building plans, cross sections or just any kind of image where you can overlay sensors on it. It is super useful for 2D views for when you don't have any use case for 3D or map view for your project.
There are three articles that will go over how to access the Image View, how to upload and manage images and how to place and configure sensors for the Image View.
