I tried another way: via the external link, Embed or HTML code. Embedding and HTML code didn't work, so I tried a link to a youtube movie, but still a blank screen. I wonder what I can do to show this 360 video in my photoalbum with the Tiger skin.
Use the "External content" feature instead of the external link.
1. Take a screenshot of the video and add in jAlbum as a normal JPG file
2. Copy the "Share -> Embed" code from YouTube
3. Select the thumbnail, change to Edit mode
4. Right panel -> External content: paste the code here (you don't have to specify the box size, that's automatically calculated)
5. Make album
This way you can achieve a proper embedding.
