Okay, just tried a test whereupon I put the 1em value in BOTH the CSS and the HTML -- and voila! The symbol image appears and scales as intended whether or not the user turns publisher formatting on or off.

HTML:

<p class="NoIndent">While reading the novel, when you see <img alt="note symbol" height="1em" src="../Images/note2.gif"/> together with the name of a song, the link will take you to the song on YouTube.</p>

and CSS:

img
{height:1em;}
