Before moving to the the next step, you'll want to make sure you have the gallery images imported into Unity.
Our project is themed as an art gallery, and because of this we are dedicating individual gallery prefabs to portraits, landscapes, and sculptures. However, you are free to use whatever theme makes sense for your project. We envisioned this template being used to craft employee-training tools, college virtual tours, cultural site visits, and professional development applications. So, use your imagination and stretch the project to meet your needs.
Because we chose an art gallery, we used Google to collect common images to match the theme. Once you have collected your images, move on to the next step.
