• Now go to the function cg_get_title() (on line 99)

Replace the whole function with:

    private function cg_get_title($single){
        global $cg_url;
        $excerpt = my_excerpt($single->post_content,$single->post_excerpt);
        if($this->params['title']){
            $title_array = get_post_meta($single->ID, $this->params['title']);
            $title = $title_array[0];
            if(!$title){$title = $single->post_title;}
        }
        else { $title = $single->post_title;}
        $returnlink = ($this->params['lightbox'])? ('"'.$cg_url.'/includes/CatGridPost.php?ID='.$single->ID.'" class="cgpost"') : ('"'.get_permalink($single->ID)).'"';
        $cgfontsize=$this->cg_get_font_size();
        $cgtitle='<div id="cgback" class="cgnojs '.$this->params['showtitle'].'"></div><div id="cgtitle" class="cgnojs '.$this->params['showtitle'].'"><p style="font-size:'.$cgfontsize.'px;line-height:'.(1.2*$cgfontsize).'px;"><a href='.$returnlink.'>'.$title.'</a></p><p><p style="font-size:'.(0.8*$cgfontsize).'px;line-height:'.(1.2*$cgfontsize).'px;">'.$excerpt.'</p></div>';
        return $cgtitle;
    }

• Open "PLUGIN_DIR\category-grid-view-gallery\js\cgview.js"
• Replace Line 11 and 12 by this:

    $(d[0]).stop(true,true).animate({height: '100%'},200);
    $(d[1]).stop(true,true).animate({height: '95%'},200);

• Open "PLUGIN_DIR\category-grid-view-gallery\css\style.css"
• From Line 52 to Line 67,

Replace height:35%; by height:100%;

and Replace height:32%; by height:95%;

THATS IT ! Your Thumbnails show Post excerpt along with your Title now.
