@jonah There’s not a way to drag to re-order photos yet, so you’ll need to add them in the order you want, or save the post as a draft and then edit the HTML to move the tags around. On the web, if it’s not showing you the HTML, you can hold down the option key (alt on Windows) while clicking edit.

@help having the option to edit the raw text of the post is more what I would’ve hoped for, so the option key sounds like a solution. It would be very helpful to have that indicate somewhere in the UI that that is available
