Optimal Performance: SVG vs JPG for E-Commerce

Department>Category> 1.jpg, 2.jpg, etc OR an SVG In a Category I gotta load <~100 images, what would be better a set of JPEG's fetched by filenames or is any way around where I can pre-load an SVG and serve the thumbnail images from it as I suppose that would save us a lot of loading calls to the server. Also what is the optimal image format to use for images.

P.s. I'm using MEAN Stack with Bootstrap.

I think probably the best way to go is to not use SVG at all. Instead get all of your jpg images combined into one file and use css image sprites. That way by loading one image you will load all of the individual images at one go. It will be very efficient and you will still have access to each image individually.
