Hi there,

You could optimize some things. First it is the best option to compress your images with a tool like Compressor. This tool will reduce the weight of your images.

Then you could use a cache plugin like WP Fastest Cache. This plugin will cache the files on your website and serve them to your visitors if they visit your website. On this way each file doesn't need to be loaded each time them visit your website or click through internal pages because the are served from the cache. Your website loading time will be a lot faster.

If you have any questions, feel free to ask
