Thumbnail titles on hover

I’d like to know if it’s possible to have the titles for the gallery titles hover over the thumbnail rather than under like here: https://lucnadeau.ca/galleries/ or here: https://lucnadeau.ca/galleries/caribous/ ?

Take a look at these: thumbnail titles hover

We had something like it in the past, though I think in Pangolin and Kookaburra album sets, it’s currently not possible. If I recall correctly, should be possible using Pangolin Journal, but I know the barrier to entry on that module is so high, most people don’t use it. Video here, though, if you want to check it out:
