How to increase hight of the module HOT NewsFlash

Please advise how to increase the hight of the HOT News Flash module. As shown in the attachment, I am facing problem to see the module properly.

Hi,

you have parameter "Height of the images" in module settings.

yes, but it does not work well. I am not a profesional programmer but I have changed the default.php, and it works well. I ca=hanged following;

$tabHeight = $imageHeight / 1.3 ;
$infoWidth = $moduleWidth - $tabWidth - $imageWidth - 10;
$imageWidth2 = $imageWidth + 8;
$imageHeight2 = $imageHeight - 5;
$hfnheight = $tabHeight * $tabNumber + 40;
$hfninfoheight = $hfnheight -10;
.
.
.
#featured {
width:'.$moduleWidth.'px;
position:relative;
border:'.$borderWidth.'px solid #'.$borderColor.';
height:'.$hfnheight.'px;
background: #'.$moduleBackground.';

.
.
.
#featured .infotext {
width:'.$infoWidth.'px;
height:'.$hfninfoheight.'px;
overflow:hidden;
