So I'm kind of a noob as far as the web design scene goes, but I'm really not sure why this isn't working. In XML, I have this string to embed a picture into the site...

<picture xlink:type="simple" xlink:href="dirk.jpg" xlink:show="embed" xlink:actuate="onLoad"/>

and I'm really not sure why it isn't working. I gave the element a box in the CSS file and whenever I click on it it highlights the box, but no picture. I have also used other actuate options such as new and replace, and those work, but I can't get anything to embed.

Any help would be appreciated.
