    17 It is likely that ImageEngine will shave off 50-60% of data traffic generated by images on your site. To better support mobile devices, ImageEngine relies on WURFL for server side device detection in cases where responsive images and client hints fall short.
    18 
    19 WP ImageEngine is compatible with the changed `<img>` tag introduced in Wordpress 4.4, while still providing full support for older versions.
    20 
    21 The plugin will prefix your image `src` (URI) with your personal hostname which refer to the image optimization servers. In addition, Client Hints will be enabled by adding a meta tag in your markup.

     23= Responsive Images Support =
     24
     25WP ImageEngine is compatible with the changed `<img>` tag introduced in Wordpress 4.4, while still providing full support for older versions. For Wordpress version 4.4 and above the plugin will optimize every version of the image referenced in `srcset`.  ImageEngine will prefix your image `srcset` and `src` (URI) with your personal hostname which refer to the image optimization servers.
     26
     27= Client Hints =
     28
     29The plugin will enable Client Hint support for your site. Client Hints, with information about the viewport size, device pixel ratio and actual image size, are added to the image request (HTTP header) enabling ImageEngine to resize the image with surgical precision.
     30
     31= HTTP2 support = 
     32
     33HTTP will give additional performance improvement on the network level. WP ImageEngine supports HTTP2 over SSL, which means that if you serve your sites and images by `https://`, ImageEngine will automatically serve all images over HTTP2.
     34
     35= WebP =
     36
     37WebP is a lightweigh image format with great quality. WebP is well supported by browsers. ImageEngine will detect if the end user's browser supports WebP and automatically convert any format to WebP to increase performance.
