You have to change 3 files
1. wp-content/plugins/frontpage-slideshow/frontpage-slideshow.php

In line 81 replace the similar with
$fsentries[] = array('title' => $title.' ', 'image' => $image, 'comment' => $comment.' ', 'button-comment' => $buttoncomment.' ', 'link' => $link, 'post_id' => $fspost->ID);

2. wp-content/plugins/frontpage-slideshow/templates/your-template/template.php

In line 54 replace the similar with

$fscontent .= '<li id="fs-entry-'.$id.'" class="fs-entry">';
if(has_post_thumbnail($entry['post_id']))
{
    $fscontent .= get_the_post_thumbnail($entry['post_id'], 'large', array(
        'class' => 'fs-skip fs-img',
        'id' => "fs-entry-img-$id"
    ));
    $fscontent .=  get_the_post_thumbnail($entry['post_id']);
}
else $fscontent .= '<img id="fs-entry-img-'.$id.'" class="fs-skip fs-img" alt=" " src="'.$entry['image'].'" />';
$fscontent .= '<div id="fs-entry-title-'.$id.'" style="position: relative; top: -44px;" class="fs-title">'.str_replace(' ','',$entry['title']).'</div>';
$fscontent .= '<span id="fs-entry-comment-'.$id.'" class="fs-skip">'.$entry['comment'].'</span>';
$fscontent .= '<span id="fs-entry-link-'.$id.'" class="fs-skip">'.$entry['link'].'</span>';
$fscontent .= '</li>';

3. wp-content/themes/your-theme/functions.php

Add if you don’t have it already (some themes have this activated) at the bottom

set_post_thumbnail_size(x, y, true); // Where x is the width of your buttons and y is the height

Wish that this helps you.
