Hello. I want to use a recipes microformat on my cookbook site. I need to use class="photo" in the img HTML tag with the source to the image of the recipe somewhere on the page to show the photo of the recipe. But img tag is parsing as the simple text? for example, this article text  will show a full-size image between " symbols. How can I use the "class" parameter with the tag  ?
