update: I found that I was able to go into the widget.php file of the plugin and make the following change to get it to work.
if ( isset( $data[‘images’] ) && $data[‘images’] && $post->thumbnail_id )
echo ‘<div class=”photo”>’ . get_the_post_thumbnail( $post->ID, array( 75, 75 ) ) . ‘</div>’;
changed to
if ( isset( $data[‘images’] ) && $data[‘images’] && $post->thumbnail_id )
echo ‘<div class=”photo”>’ . get_the_post_thumbnail( $post->ID ) . ‘</div>’;
I am curious to find out if this change will be overwritten when the plugin is updated?
