I experimented for a while to find the proper HTML code to format comments on photos. What prompted it was a revision of Internet Explorer which no longer rendered properly the HTML I was using. So, if you want to be cool like me, sandwich your comments between the two bits of HTML you see in today's photo. You will be amazed at how your friends will think you are cool and all the women will be chasing after you like they have chased after Larry for all these years.
One more thing: don't forget to tick the "html flag" button in your gallery attributes.
That makes the text a lot easier to read---no need to drag one's eyeballs from one side of the screen to the other. All this time I have been using the Enter key to control the width of my text. I'll have to try the method you suggest. Thanks for the tip.
