Adding alt tags and renaming images is always a pain and I often forget to do it. This plugin is perfect. It will take care of everything for you. Highly recommended.

This plugin is amazing, it saves a lot of time by optimizing image names and alt with precision. People always forget to rename pics and set alt (important for SEO and accessibility) or they do it wrong. This plugin takes care of everything!

You can only optimise 3 images before your credit runs out and it implores you to buy the premium version. It just really irked me, reading the great reviews and trying out the plugin myself to find out that I can only optimise a pathetic amount of images. I could have optimised the alt attributes of ten images manually in the time that it took me to run the plugin. The developers know that the whole idea of needing a bulk alt image optimizer is because you have a plethora of images that need optimizing, so to offer you a pathetic three image credit limit is scandalous. I'd be more than inclined to pay your 11.99 monthly subscriptions if your trial service wasn't so incredibly laughable.
