title: Official image host for GitHub projects?
body: <p>Whenever I need to include a picture in a GitHub project's README file I usually just stick it in a Screenshots folder and <a href="https://stackoverflow.com/a/12997531/969967">relatively link to it</a>. However this unnecessarily bloats the file size of the project, especially if I include an animated .gif of the project in action. </p>
  
  <p>I've noticed in a couple popular Github iOS projects (like <a href="https://github.com/mutualmobile/MMDrawerController" rel="noreferrer">MMDrawerController</a> and <a href="https://github.com/gotosleep/JASidePanels" rel="noreferrer">JASidePanels</a>) that the images are NOT relatively linked, but rather they exist on a domain I've never seen - "<a href="https://github-camo.global.ssl.fastly.net" rel="noreferrer">https://github-camo.global.ssl.fastly.net</a>". Navigating to this site directly doesn't work and Google searches bring up nothing. So for my question: is this site affiliated with GitHub, and how does one get his/her images uploaded here? Of course I could always use a generic image hosting service but I'd prefer to use one that has official ties with GitHub (if such a site exists). </p>
