Thanks Shawn for the quick response. I should have included more details. Here's a sample of what I'm working with (it may not be syntactically correct).
<div id="slider" class="nivoSlider">
<img src='http://www.cookingexchange.info/wp-content/uploads/2013/03/8384725_xl-resized.jpg' alt='' title='#sliderCaption1' />
<div id="sliderCaption1" class="nivo-html-caption">

It's the image credit link above (it shows up as the red link under every slider image) that I want invisible unless someone "mouses over" it. Is this possible? Thanks again.
