In the editor
Use the img tool in the toolbar to insert the HTML code. Works for images on the web or from our library.
Works first time for a post (initial posting of a thread) but in comments, you'll have to go back and edit the comment for it to work. For some reason html does not get accepted until you edit.
YouTube embeds in the initial post get zapped too. Don't know why. Put them in an edited comment.
Also, you can use the paragraph tags to control your subject line. Comment using only the body window, go back and edit with the tags (edited)
