Insert Image in Layout -> Content (Startpage / Home)

we are using Rocket Chat SNAP Version on a Ubuntu Server and i would like to know, if its possible to insert a image into the Layout -> Content Section?
In the Content Section i can write some information to the Startpage/Home.

I can format the text with html code but i can not insert a image. Where should i put the image file in the snap directory or how can i insert a image to this content?
