Making an emoticon or any inserted picture "talk" is actually quite easy and can be done in a few simple steps.
When you are typing in your post you should see a small check box at the bottom left of the window.
When you select the box as indicated in the picture above you will see the HTML code that represents the message you're typing. The code for the example emoticon would look like this:
<DIV><IMG height=19 src="http://sc.groups.msn.com/themes/R9c/pby/img/emoticons/emsmiled.gif" width=19></DIV>
To hide a message behind the emoticon we add a small bit to this code as indicated in red below:
<DIV><IMG height=19 src="http://sc.groups.msn.com/themes/R9c/pby/img/emoticons/emsmiled.gif" Alt="your hidden message here" width=19></DIV>
Its important to note that it comes before the part marked width.
Once you have added your text you simply unselect the small check box to return to the normal view.
Why not give it a try? Its not as hard as you might think. Lets have some fun!
