Jim’s software looks for any HTML in your posts.
If it finds “none”, then your post shows up just as you typed it.
If it finds “any”, then it interprets the entire post as HTML.
So, you have to use HTML correctly throughout your entire post,
or not use it at all.
the software does not allow for mixed/partial HTML usage.
You posted the image in correct HTML, but the rest of your post did not conform.
