Hi,
I see that you have some problems with adding images to your posts.
Remeber to choose "direct" link instead of "html" when you copy image address and paste it in Steemit. If you see your blog post being incorrectly formatted, you can always go and edit it up to 12 hours after posting.
Here is more info about how to do it:
