Tummy Time review for Tiny SEO Speed Image Optimizer

I have been using Tiny SEO for images optimization, and SEO metadata automatic generation. It's been working great, saving me a lot of manual work! The support is also very reactive, and helpful. Regarding the other features, like speed optimizer. I am not using them as it wasn't advised to do so by my theme provider. I am on a paid theme, already SEO-optimized.
