(I'm trying figure out how to post an image with text above or below it instead of being to the side when it actually posts. [Preview always looks ok, posting doesn't.] If this messes up, please ignore it!)
AHA! Well, that was easy. Prob. should be added to the HTML Sandbox.
Just add a paragraph break at the end of the text, same as with other HTML.
Now if only I could figure out how to put HTML (say a pic, italics, or paragraph breaks) AND a hot link in a post without killing hot link...
