Image height and width for new listings

[jonten123 +]

Hello,

I changed the width and height for the images in function.css_listings_horizontal.php.

$image_width = 100; to $image_width = getimagesize();

$image_height = 86; to $image_height = getimagesize();

The images looks all right now, not stretched in any way but they do not appear in IE version 8. I can see them in firefox and chrome but not in IE. Did I do something wrong?
