Fixing Grainy Image- Adobe Photoshop Elements

I have some photos taken with a digital camera that appear very grainy. I need to fix them so that they can be used in a wedding album. How can I use Adobe Photoshop to get rid of the grainy look and make the picture look more professional quality?

Your subject line says Elements but the message doesn't. If you are using Elements, please post in the Elements forum. You should also post a link to the photo in order to give folks some idea of what it looks like.
