Size
Controls how the image needs to be resized. You can use both &w= and &h= parameters or only one of them: the other dimension is automatically updated.
Width &w=
Sets the width of the image, in pixels.
html
<img src="//t.net.co/?url=t.net.co/lichtenstein.jpg&w=300">md
Height &h=
Sets the height of the image, in pixels.
html
<img src="//t.net.co/?url=t.net.co/lichtenstein.jpg&h=300">md
Device pixel ratio &dpr=
The device pixel ratio is used to easily convert between CSS pixels and device pixels. This makes it possible to display images at the correct pixel density on a variety of devices such as Apple devices with Retina Displays and Android devices. You must specify either a width, a height, or both for this parameter to work. Use values between 1 and 8.
