Easy to Use SEO Tool

I never have time to add alt text to an image but it is necessary for SEO. So I was very pleased to find this easy to use plugin that analyzes your image and adds the alt-text for you. Bought the premium plugin and just auto added alt-text to over 250 posts. One suggestion for the plugin I have is to not having an option to allow the text auto add the same description to the caption description box as I read that this would not be good for SEO.
