Cannot produce PDF using imagesdir having a URL

[rodneyFinlay]

I need to embed images in the PDF from a central repository referenced by a URL pointed to the base location. During the invocation to asciidoctor-pdf I'm getting the below error:
undefined local variable or method `image_base_uri' for #Asciidoctor::Pdf::Converter:0x007fef9402fba8
Did you mean? image_page
Use --trace for backtrace

All documentation seems to agree that if the base URL is in the imagesdir attribute that the image:: block should simply embed the image at that position.

Excerpt from adoc file:

:imagesdir: http://upload.wikimedia.org/wikipedia/commons

Oops, it looks like I made several errors when programming this behavior. Thanks for bringing this to my attention! I've issued a fix as PR #468.

Even with this fix, you still need to use the https version of the URL since the wikimedia server does not support a redirect to https (at least not when using the built-in Ruby HTTP client):

Great news. Thanks for addressing this problem. When is v1.5 due to go to beta / GA?

I'm not sure about beta, but I'm trying to get another alpha out asap. I've just been very busy lately, but it's going to happen any day now.
