MinePic

If you're looking for something hard, you're in the wrong place.
This is the simply way to get an avatar:

<img src="https://minepic.org/avatar/username" />
<img src="https://minepic.org/avatar/uuid" />

Bigger is better. Try:

<img src="https://minepic.org/avatar/512/username" />
<img src="https://minepic.org/avatar/512/uuid" />

If you need 2D skin:

<img src="https://minepic.org/skin/username" />
<img src="https://minepic.org/skin/uuid" />
