Slider in Pro Theme: read more link on whole image

Hi,

i’m trying to modify php code from the slider. i want that the whole image is linked to the same url as the read more button. how can i do this?

  <div class="slider-main">
       <?php
			$slAr = array();
			$m = 0;
			for ($i=1; $i<11; $i++) {
				if ( of_get_option('slide'.$i, true) != "" ) {
					$imgSrc 	= of_get_option('slide'.$i, true);
					$imglink	= of_get_option('slidelink'.$i, true);
					$slidebutton	= of_get_option('slidebutton'.$i, true);
					$slideurl	= of_get_option('slideurl'.$i, true);
					if ( strlen($imgSrc) > 10 ) {
						$slAr[$m]['image_src'] = of_get_option('slide'.$i, true);
						$slAr[$m]['image_button'] = of_get_option('slidebutton'.$i, true);
						$slAr[$m]['image_url'] = of_get_option('slidelink'.$i, true);
						$m++;
					}
				}
			}
			$slideno = array();
			if( $slAr > 0 ){
				$n = 0;?>
                <div id="slider" class="nivoSlider">
                <?php 
                foreach( $slAr as $sv ){
                    $n++; ?>

#### here i want the picture is linked to url from button ####
<img src="<?php echo esc_url($sv['image_src']); ?>" alt="<?php echo esc_attr($sv['image_title']);?>" title="<?php echo '#slidecaption'.$n ; ?>"/>

<?php
                    $slideno[] = $n;
                }
                ?>
