I copied over the text, did a bit of reformatting, as copy/paste messed things up a bit - that bit could probably be improved. For this old post, the images were once in Flickr, so they were all still there. That made a pretty simple option for adding them to here - just embed them from Flickr. I removed the script it adds, and removed the sizes so they can resize. Not necessary, but keeps things simpler. They still link to the Flickr images, which is what they require for hotlinking.
I used the Location: setting in the frontmatter to make the post respond to the same URL it has on my current site. That way, if I decide at some point to move the domain over here, the same URLs will still work. Google shouldn't notice much other than things getting faster.
