Best way to add additional products photos

I would like to add some additional images to the product pages, I thought about having a single featured image but including a side and back view as well as a front view in the middle which would end up being displayed in the grid view. This could work but need to have a play with the image dimensions so the middle front view is cropped in the grid.

I tried adding some additional images to the product content but would prefer the images to load in a shadow box (like the featured image) rather than just linking to the site.

Just wondering if there are any other ways which have worked well for people I would ideally like the images to be shown alongside the featured image at the top and load in a similar way and be able click through to the next images.

Any ideas would be greatly appreciated. Cheers, Harry
