Thank you, thank you! I've been trying to figure this out, off and on, for a month. Thanks, again.

Many Thanks Worldspark..

I figured out the problem. There is a section in "functions.php" that controlled the size of the picture as well.

Steps to change slider size.

1. Go to the css stylesheet in Wordpress editor. About 40% down on the style sheet there is a section called *Slider Style*. We are interested in editing the sixth and seventh paragraph under slider style which contain the size and width of the slider box and boarder. shown below.

}
ul.pxs_slider li a {
display:block;
margin:0 auto;
height: 419px;
width: 936px;
border: 12px solid transparent;
background: url(images/sliderimg_bg.png) repeat-x left center;
-moz-box-shadow:0px 0px 20px rgba(0,0,0,.3);
-webkit-box-shadow:0px 0px 20px rgba(0,0,0,.3);
box-shadow:0px 0px 20px rgba(0,0,0,.3);
}
ul.pxs_slider li a img {
display:block;
height: 419px;
width: 936px;
}

2. Edit the height and width that you desire.

3. Click update.

4. Go to the theme functions page. Find this line: add_image_size( 'my-slide', 936, 419 );\

5. Change the height and width to the same as you did in the css sheet and update.

6. Make sure and crop your featured images to be the exact size that you changed this ratio to.

Your slider should now be larger or smaller without blurry photos.

I hope that this can help somebody. It took me hours of frustration to figure out how to get it to work properly.

Cheers,
