Re: Performance problem: Images are resized in HTML or CSS


Hi Markus,
Thanks a lot for your detailed reply.

search engine optimization (it will result in bad ranking).

If you are worry about SEO, than ONLY this point will not affect SEO. We know the number of websites having number one position against different keywords on Google but serving retina images. SEO is a very broad field and complex topic. Following two URLs will help you a little about search engine ranking factors,

Scaled images will relate to Page Speed only which is one ranking factor. But, Page Speed can be improved by the combination of several other factors.
WordPress has introduced the Responsive Images support in its latest release and it is enabled by default. We are working on it to serve right images without affecting the quality (As we have observed blurred images on Retina devices).

Please feel free to ask additional questions.
