Hi @Karilara I ran your site through the Shopify Analyzer and it looks like lazy loading can help improve your speed:
That's a free tool my team built for the community, it's geared specifically for Shopify sites with scoring based on over 1,000 Shopify sites we've optimized.
You can see the details of your analysis here: https://analyze.speedboostr.com/result/fwc48eby3r, then click on Lazy Loading to see which images are not being lazy loaded.
Lazy loading basically loads images as the user scrolls, instead of all at once, saving time when loading the page. Details here: https://speedboostr.com/shopify-lazy-loading.
If you need help with anything give a shout to my team at speedboostr.com/contact.
Good luck on your optimization project.
