Tiny SEO Speed Image Optimizer

Rating 5 stars because even though it seemed to not work with some products that regenerate images for personalization purposes (e.g. ShineOn) the support was ever so kind and fast to respond. I decided to cancel and roll-back any optimizations made. I do hope that there might be a way to only optimize images based on type (store, collection, vendor, product grouping etc) rather than all or nothing. I may look at this again in future.
