The blogspot's editor is very old...
Mars Edit (shareware 30-day trial)https://red-sweater.com/marsedit/
Nice: autodetect you blog.
Quickly scan your iPhoto Photos, Lightroom, or Flickr libraries, and insert images into your blog post with the click of a button.
Build a template to match your blog, then let MarsEdit's live preview show you how your posts will look before you publish them. Use Markdown? MarsEdit will preview that, too.
Combine the power of MarsEdit with your favorite editor. Integrates cleanly with BBEdit, TextMate, WriteRoom, TextWrangler, or any editor that supports the ODBEditor suite.
"insert image" ---> src="https://lh3.googleusercontent.com/..."
It's different from the blogspot editor---> "https://XX.XX.blogspot.com/...."
Then flipcard does not work.
