image to webp

[majuro16]

convert images to webp (eg. with this link)
https://image.online-convert.com/convert-to-webp

and update html

How to:
You use webp like any image:

<img src="img.webp" />

However since it's not always supported (see http://caniuse.com/#feat=webp), you can use this to set a fallback:

<picture><source srcset="img.webp" type="image/webp"><source srcset="img.jpg" type="image/jpeg"><img src="img.jpg"></picture>
