This may be old news to some, but I was delighted to discover that I could use the blogger image uploader to put in a series of photos and then go to the edit html (as opposed to the tab labeled compose) and then cut and paste the photos to where I wanted them in the post.
Since I have been having issues with Hello and haven't tried flicker yet, it seemed a simple solution.
If you try this, I think it is easier to write your post and then move the photos.
Hope this helps someone.
