In https://gidikroon.eu/2019/03/18/test-post/ the included photos were just lying around on my device. They happen to be posts by Miranda Cosgrove on Instagram. It was just a test post, it’s not a post about her.
This is a test post from Indigenous for Android, the micropub client. I’m not using microsub yet, which this client can also do.
Test post of using micropub to wordpress to activitypub. Photo is of Miranda Cosgrove being adorable in Mickey Mouse t-shirts, from Instagram.
So, micropub to wordpress went fine, if you include only one photo.
It doesn’t publish to activitypub however. Maybe with this edit in wordpress it will. It did publish to activitypub after all, it just takes a while.
