There are two ways to add a thumbnail to the Carousel.
1) Add Scene - Navigate to a 360 by clicking on the arrows in the image that are not already in the carousel and click the “Add Scene” Button
2) If you used islands, want to add a 360 from a different tour, or are having difficulty navigating TourBuilder to the 360 you want to add, you can add a 360 by using a PanoID.
To switch the add scene button to add by PanoID instead, please hit the “Alt" button on your keyboard.
When you click on add by panoid you will see a prompt to ask you to enter a panoid.
There are a couple of ways to find the panoid for a 360 that you want to add.
1) Navigate to a 360 on the main screen and click on the copy panoid button.
2) If you want to use a Google Map URL to grab a panoid using this tool. https://login.tourbuilder.com/#/tour/panoid/from/maps/url. To use the tool, simply navigate to a 360 you want to add on Google Maps and paste the URL. This will then bring up a picture of the 360 and some information from Google, including the panoid.
