You are welcome! My wife and I also use the Google Blogspot (here and here) and when my original idea was not working (because I had not made the images “shared”) I was thinking of using the blog storage as an alternate - I just wanted something slightly (very slightly) simpler.
For those not sure how to do this link in the description or journal, you can just add the following:
<img src=your copied image link goes here>
<img src=https://static.inaturalist.org/attachments/users/icons/83288/thumb.png?1475546514>
results in 
The bottom line is there are other external resources available for image storage to link them into a habitat photo for the observation description (thanks for that idea @kiwifergus ) or to link them into a Journal habitat post.
