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 a hard time navigating in Panoskin 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 cople of ways to find the panoid for of a 360 that you want to add.
1) Navigate to a 360 in 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.panoskin.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 in. This will then bring up a picture of the 360 as well as some information about it from Google including the panoid.
