Image

This field can be used to add images to each data point. These images will be displayed on the node. 

Unlike Drill Down Graph PRO, which requires converting image URLs to base64, Image field in Drill Down Map PRO can contain direct image URLs.
When using Cluster Nodes, individual node images in this field will not be applied to the cluster. However, if your selected Max Clustering Zoom Level permits the user to expand clusters into separate nodes, each location node can display an image from this field.
