Most (all?) of the links in that post no longer work due to a change in rpgmapshare.com's gallery hosting engine, but it seems that some part of the old engine is working, as the first two links in the thread do seem to work. Accordingly, I've tested the formatting of the top two addresses with the ID numbers indicated by the non-functional links, and they all pretty much worked!
