Remove picture from Text Editor

[emoes]

Hello,

 

I look on this forum to find the solution regarding removing the frontpage picture from the "Welcome Text editor"

I found a old post (Regarding Prestashop 1.5)  that there should be a delete buton, but could not find it. (see screenshot)

But I still have a picture on miy font page including the text.

Is there a way to remove the picture (using the backend) instead of changing some PHP code?

 

I'm using Prestashop Version: 1.6.1.2
