Tiny SEO Speed Image Optimizer

I can't say this actually fixed my problem, but it does help fix a lot of the problems fairly easy. Such as adding Alt="names" to all the images, fixing the broken links, resizing images, lazy-loading (although I believe Shopify kind of already has lazy loading rendered into the images), and more features.

As it stands, my page speed hasn't really increased, maybe marginally, but it still removed a lot of the headaches. I give this 5 stars mostly because the customer support was very helpful.
