The broken image source URL is

https://github.com/robpike/ivy.git/raw/v0.1.0/ivy.jpg

but it should be

https://github.com/robpike/ivy/raw/v0.1.0/ivy.jpg

Pkgsite tries to convert a relative markdown image URL to an absolute URL by prepending the repository URL, but for some reason the repository URL ends in ".git", as can be seen in the repository link on the right side of the page. Probably because the "go-import" meta tag under https://robpike.io/ivy?go-get=1 ends in ".git":

<meta name="go-import" content="robpike.io/ivy git https://github.com/robpike/ivy.git">

https://golang.org/cmd/go/#hdr-Remote_import_paths says:

"The meta tag has the form:

<meta name="go-import" content="import-prefix vcs repo-root">

The repo-root is the root of the version control system containing a scheme and not containing a .vcs qualifier."

Change https://golang.org/cl/288612 mentions this issue: internal/source: trim .git suffix from repo URLs

Thanks for the accurate diagnosis, @fzipp.

The .git also broke source links.

We deploy daily so this should be live by tomorrow.
