I think I’ve found the idiomatic way to create a blog post for a SharePoint blog: MS Word. If you create a post via the “Create a post” link, you have to hand-format all the html yourself. Sometimes I may do that for greater control, but it’s really clunky if you want to add an image to your post. So instead of “Create a post”, click “Launch blog program to post”.
When I did this from Firefox, I received this message:

I clicked “Launch blog program to post”, and after some first time set-up and a warning about usernames and passwords flying around, Word appeared with a new Blog Post section in its menu:
I typed in my title, typed up this post, and – most convenient of all – just pasted in the screenshots, then pressed Publish, and there it was in my blog. Nice!
