Very slow page load- URGENT HELP

My entire website has good response rate, except one page called “SHOP” which has most of the images of the products. Although I have uploaded low resolution thumbnails and also turned on lazy loading, it still takes about 20 seconds to load. Especially on mobile the Shop Page has a terrible response.
I suppose the tabs section (which is the only section in the page containing all the product images) is trying to load everything at once.
