[Plugin: WP Featured Content Slider] Float images left instead of right?

You edit the content-slider.php file. Below the CSS styling code, search for the line that starts with (just before the endforeach):

<li><div class="content_left">

Let these pieces of code in that line switch places:
<div class="content_left"><h2><a href="<?php //the_permalink();?>"><?php //the_title();?></a></h2><?php //the_excerpt();?></div>

<div class="img_right"><a href="<?php //the_permalink();?>"><img src="<?php //echo $thumb;?>" /></a></div>

Put the image part before the content part and you’re done.
