The images on the wiki documentation return not found

[VanPaitin]

I am trying to use this gem and I am perusing the documentation. I observe that the images that illustrate how the tags look like are not displaying. I tried to copy their src attribute and load it directly from the browser but the page returned Not Found. Here is the link to the wiki document I am talking about
