Very interesting, some decent-sized images in there, too.
There's a new thing that is a Counterparty / Ordinals hybrid called Stamps where image data is being stored in outputs as opposed to inputs. A few Dogeparty peeps have been experimenting with it as well (just started yesterday), but the changes haven't been made to the explorer to view base64 encoded images yet, as it has for the Counterparty explorer.
Doginals thus far has been a flop -- apparently every Doginals project was a rug. The Doginals explorer is having problems and the inventor of a competing numeration system for his "Dogecoin Rocks" has gone AWOL. Turns out you need to have the ordinals system fully applied to Dogecoin first or you won't be able to know which doge-satoshi is the ordinal, and thus can't move it, LOL.
