What is the default sort order in the Gallery shortcode?

This is what I have now for shortcode.
Is there a way to have the latest upload appear at the top? I would have assumed that was the default.

[rtmedia_uploader]

[rtmedia_gallery global=“true” context=“media” media_type=“photo”]

The default behavior of Gallery sorting is latest uploaded media comes first.

I can’t figure out how to show all media images that get uploaded. It is only showing the ones uploaded via the page that has that shortcode on it. I really want everything to show that is uploaded in posts as well as from that gallery page I have the shortcode on. Any suggestions?

You need to write the context_id of that page in gallery shortcode from which page you want to show images.
