Unless you're wanting people to save the images on the landing page, please optimize the images. WebP and only as big as they need to be rendered.
If I go to a service designed around images and it's taking 5 seconds on a SOLID fiber connection to fully download, it doesn't give me confidence that I'm going to get a fast experience in the rest of your site (even if it's not directly related).
