Trouble with pictures

I was trying to post a picture or two in some content I’ve created, but the only solution I could find was to paste the link to the picture or to my blog, where the original post appears with the picture.
Is there a way to put a picture other than the thumbnail one in the middle of the content text?

We don’t support images in the text, so you may want to add links to the pictures (or a link to the original blog post) in the Notes section so learners can check them out.
