Not sure I understand your question.
The image tag (which is HTML) is used to display images. So in your code you would have something like: <img src="images/myimage.jphg" />.
If you wanted to generate the image dynamically, say with an image name stored in your database, you could use PHP to create the recordset and then populate the file name - similar to this: <img src="images/<?php echo $recordset_row['image']; ?>" />
Not sure what else to add... maybe you can provide more specific goals for what you are trying to accomplish.
