[Plugin: Slideshow Gallery] Text Opacity

I found this code in the gallery-css.php file and changed the opacity up to 80%, but that seems to be about as good as it’s going to get for now. Adjusting the opacity seems to be linked to both the text and the background, and I’m not sure how to split the two.

<?php echo $styles['infobackground']; ?>; color:<?php echo $styles['infocolor']; ?>; overflow:hidden; z-index:200; opacity:.8; 

filter:alpha(opacity=80); }
