不需要开启，如果开启的话，有可能使图片变的更大。如果你注意一些网站的 img 资源时，就会发现他们都没有开启 gzip

Don’t use gzip for image or other binary files.

Image file formats supported by the web, as well as videos, PDFs and other binary formats, are already compressed; using gzip on them won’t provide any additional benefit, and can actually make them larger. To compress images, see Optimize images.
