A: Yeah, if you're just doing one-off compression, I think you would be better off sticking with what you are doing. I mean, our plugin would make it easier in that you just have to upload the image to your site and it would take care of it for you. But, generally, our service is more about either making your site quicker or saving you space on your server (by compressing your images). If the images have already been compressed, and you aren't interested in a CDN or JS/CSS optimization, then there's probably not much that our service would do for you.
