N.B.: However, it can't render 100% width/height parameter! It makes 100%=100px thumbs. As the use of this dynamic % param is important for me on my site, as well as for many other site owners, so in this case such a good extension unfortunately becomes useless... Hope the developers solve this issue, then I'd love to use the plugin!
N.B.#2: Another note... Now when enabled plugin captures ALL resized images on site. However, it would be good to have only some categories selected, articles too!
So overall it's a great extension, surely the best in operation from all I've tried in the category, but still needs some essential developments.
