Hello,
To Disable responsiveness you have to comment out all media queries located in the template.css file.
To unlink the homepage image you will have to modify the file default.php in templates/nokkori/html/mod_k2_content/Slideshow/ or templates/nokkori/html/mod_nucontent_items/Slideshow/
In around line 54 there is this block of code
<?php if($params->get('itemImage') && isset($item->image)): ?>
<a class="moduleItemImage" href="<?php echo $item->link; ?>" title="<?php echo JText::_('K2_CONTINUE_READING'); ?> "<?php echo K2HelperUtilities::cleanHtml($item->title); ?>"">
<?php /* <img src="<?php echo $item->image; ?>" alt="<?php echo K2HelperUtilities::cleanHtml($item->title); ?>"/>*/ ?>
<span style="background:url(<?php echo $item->image; ?>) no-repeat center center fixed;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='<?php echo $item->image; ?>', sizingMethod='scale');
-ms-filter:"progid:DXImageTransform.Microsoft.AlphaImageLoader(src='<?php echo $item->image; ?>', sizingMethod='scale')"; "></span>
</a>
<?php endif; ?>
Just replace the <a> element with a <span> element and remove the href and title attributes. Then in your custom.css file add this
#slideshow .itemsWrapper .moduleItemImage span {display:block;width:100%;height:100%;max-height:100%;background-size:cover!important;}
