The hotspot settings (for icons) for your Interactive Image are located in the Customize portion of the project creator.
You use these settings to control how your hotspots appear on your Interactive Image.
There are 3 options available:
When page loads (show by default but disappear if person hovers then hovers off image)
On hover (icons only show on hover)
Always show icons (not affected by hover)
These settings will control all hotspots on your Interactive Image. Don't forget to save after making your selection.
