Thanks for your interest in EasyBlog. Based on your video screenshot, I believe you're doing great. However, you'll need to separate the paragraph of your blog into individual blocks, so that you'll be able to place the image within the blog. Check out the EasyBlog composer video here: https://youtu.be/eyuZHBbHzzY
Hope this helps. If you've any more questions, let us know.
Cheers.
