Sounds like a pretty weird thing to ask but here is what I'm looking for...
I have some custom fields on the user area in wordpress. These are then shown on the author page.
What I have right now is users enter their facebook link and it will add a facebook icon to the page. The only problem is if a user doesn't enter their url there is just a facebook icon there with no link.
Is there a way to only show the image if a url has been added?
