Interesting. It definitely used to be the case that you could use Tabber instead. I guess Fandom must have removed that. Using gallery tags is better anyway. - Edit:

Actually, you still can use Tabber. I just tested it here on Community Central. I also did an unsaved test using the gallery tag on the example page and it didn't work either. I think there must be something preventing the tabbed imaged from working properly on your wiki other than just incorrect syntax. - Edit:

I figured it out. The issue is that the second image does not exist. I guess the infobox is smart enough to realize that the second image doesn't exist so it displays its one and only image as a single image instead of a gallery with a single image.
