Hello @devries, I'm also new here. Let's see what we can find in dis place. :D
Also, you can edit your post to add the image of your sketch, below the typing space. It will load a bit and then there will result a text like this:
!{name of the image}(https: //steemitimages.com/randomletters/yourimage.jpg)
But you will be able to see the img in the preview.
Hope it helped! ^^
Thank you, played around on the site a bit before I went to sleep, think I am getting the hang of it now :)
