It seems like image attachments do not work in the current port version so I guess more users might be interested. I hope it is not rude to report a new version like this.
I tried patching the port but got warnings and errors I can not fix myself at the moment, some calls needs rework/ignoring and then getaux() should exist but does not work for me. This was in a library and I might revisit the issue when I have more time to work on it.
Sorry, been sick and didn't see this until now. I've been meaning to get back and update this, but since the world went mad, work has been extra busy.
Thanks for the legwork! I'll try to get it fixed up soon.
