If you want to go deep into what you can do just go to the wordpress site. It is almost infinit, I will add at some point selling possibilities to a secondary site.
For the time beeing lets explore images.
Here is an image:
I used the insert image tool, first insert it into the gallery then in “show” do insert into post.
I have to look at storage issues before I open video and music possibilities. We should be hosted on something like 1&1 but are not yet.
Cheers,
