Hover Image is a Rich Media format that makes an image appear to be hovering above the content of a site. The image can be moved around by using the mobile’s/tablet’s gyro and by scrolling up/down on desktops. External link upon click.
N.B. in mobile Safari browsers with iOS version 12.2 or higher, it’s no longer possible to move the ad format with the phones gyro since the default setting of “Motion and orientation access” is turned off. If turned on by the user and the target site is HTTPS, the ad format works as normal.
