@Lixon_Louis thanks for this. Looks like what I need. I'm stuck at step 4 though as there is no theme.js.liquid in Boundless theme. There is only theme.liquid and it has total 299 lines. Could you point me to the location where I need to paste this code? Thanks a lot in advance. Cheers.
Update: Never mind @Lixon_Louis wasn't looking at the right place. found .js.liquid now.
@Lixon_Louis so I've followed your instructions and I see that images are coming as gallery but there are few problems:
1. The image size is smaller on desktop (mobile is okay). Could you help on how I can increase this?
2. To move to the next image, when I select image, whole gallery is being selected:
3. Is it possible to apply this template to all existing products in one go instead of one by one?

Thanks for help!
